Since you cannot link other subreddits here, I'm going to copy and paste the post and afterwards give my breakdown. This post is also for me to practice the RP thought.

The Post

Hi everyone, I wanted some assistance and also just to get this off my chest. My wife and I have been married for three years and together before that for a year and a half. As you guys may know valentines day is tomorrow. For a while now, I have been talking to my wife about having anal sex, however she has been not very keen on it. She said she has never done it before and it scared her. However, recently I think because of my diet ( I have visible abs now) , and Valentine's day around the corner, she has opened up to the idea. And said so long as she is not feeling backed up, we could try it tomorrow. Last night my wife and I were watching TV while she was on her phone she ended up going upstairs to bed and I ended up hopping on her Ipad. My wife has her accounts synced so if she gets a text on her phone it also comes on her Ipad. Now, my wife and I don't hide things from each other we both have the same passcodes. While I was on there I saw incoming texts, I didn't look at it up and continued playing. But then I saw a text with my wife's ex name and a thing about anal sex. I started scrolling up to see the full conversation. To sum it up, my wife was telling our neighbor Katie, that me and her were going to be having anal sex. Katie asked if she had done it before, and my wife said she did it before, that her last ex Lucas, loved her butt and they did it all the time. Katie asked my wife did he have a small penis. And my wife was like no it was a good bit bigger than mine. She said it was fun , but she liked regular sex more because it wasn't as messy. That just really hurt. There are a couple sore parts about Lucas. My wife really liked Lucas, he was this tall guy that also went onto become a pediatrician. When we started dating, she actually broke up with me for a month to try to get Lucas back but he turned her down ( I didn't find out about this until after we were married). And just he has been a point of contention for a while now. With the whole Valentines day plans a lot of the whole thing about us having anal sex was the fact that it was something new that we could share with each other. The fact that neither of us did it before meant a lot to me, and just all the trust. But now hearing that she did it with Lucas before me, and then went onto hide it, and then go around telling our neighbor, whom she isn't even good friends with. Just all of it really puts a bad taste in my mouth. To be honest, I don't even want to do it anymore now. Should I tell my wife that I saw the conversation or do I just tell her that I am not in the mood. I really feel broken about all of this. If It was with another one of her ex's than I probably wouldn't care as much but the fact that it was this guy hurts a lot.

The Breakdown

Right away you can see that OP "has been talking to his wife about having anal sex". You don't negotiate with women, it will never work. Express your desire and increase your SMV so that she wants the same thing. Moving forward the wife finally agrees, tomorrow night they'll try anal. Why the change? Looks like OP is doing something right.

However, recently I think because of my diet ( I have visible abs now) , and Valentine's day around the corner, she has opened up to the idea.

We know it isn't valentines day, its the realization that she may have to work to keep OP since his SMV is rising. But why the hesitation to try anal in the first place?

She has never done it before and it scare(s) her

Hmm. Read a bit further, and OP finds her texting a friend about how an ex used to fuck her in the ass all the time.

She said it was fun , but she liked regular sex more because it wasn't as messy.

So her earlier excuse has absolutely no merit at all besides holding power over OP.

We can see her lying to increase the value of anal, making OP think its her special gift and he'll eventually earn it. We know this will never happen, and she is stringing OP along even in marriage.

Here is where the post gets cringey as fuck. OP informs us that early on in the relationship (which btw is only 4 years old, at most): **

she actually broke up with me for a month to try to get Lucas back but he turned her down ( I didn't find out about this until after we were married).

God dammit its pitiful to read. OP was a designated BB from the get go, and her ex was a Chad through and through. The ex not only got what he wanted from her, but rejected her efforts to tie him down. She found a stable BB with OP, yet she still ditched him in a secret effort to ride the CC with Chad once more. And of course she hides this until OP mistakenly married her. To add injury to insult she describes how her ex has a bigger dick that OP.

Lets see OP's thoughts on the matter.

But now hearing that she did it with Lucas before me, and then went onto hide it, and then go around telling our neighbor, whom she isn't even good friends with. Just all of it really puts a bad taste in my mouth. To be honest, I don't even want to do it anymore now.

Why the fuck isn't the dude raging?? He doesn't get it. He's bottling the natural anger up, trying to maintain the reaction society tells him is normal. At this point OP should start secretly getting his finances in order and lawyering up, theres no way the wife is not fucking someone on the side. Maybe she hasn't yet, but as proven time and time again, AWALT and it will happen as soon as the wife gets a chance.

I really feel broken about all of this. If It was with another one of her ex's than I probably wouldn't care as much but the fact that it was this guy hurts a lot.

COME ON. OP gives such a shit about this guy because deep down, instinctively, he recognized that the Ex is an Alpha, a Chad that OP cannot compete with. Of course, this is why his wife was drawn to him in the first place and why the wife left OP for a month to get a taste of the Alpha once more.

Conclusions

Now there aren't really any new takeaways from this post, but lets lay the conclusions out for shits and giggles.

-All women are the same. OP's wife did acted in line with her evolutionary programming; she sought the alpha dick regardless of the consequences, and at the same time secured a provider for the long term

-OP reacts in the worst possible way, because OP is almost a total beta. If it wasn't for the 'getting in shape' aspect, he'd be 100% beta. Not only does he not get angry about the wife lying to him and leaving him for a Chad only to come crawling back, but OP sis decided whether or not to tell his wife or go on like nothing happened. Jesus christ, guys everywhere take note. This is the exact opposite of how you should react. You should silently change demeanor while lawyering up and preparing for divorce, and letting your wife's hamster run on and on about why you've changed. Maybe you'll even get that last anal fuck you've been wanting before you inform her that you're leaving.
