2 Questions: Separation & Don't Leave the House

First post. Been lurking for some months. Didn't want to post until I finished all the sidebar but shit hit the fan and I have some questions.

Sorry about format/spelling/etc. Posting from my phone on my lunch break.

I'll post the questions first, since my BG is so long. Questions can be answered in a vacuum tbh.

1. She asked for a separation. I did a search and half were men doing the separation, other half the wife. And no concrete advice (that I found). My thing is, why get a separation? Why not just go full out with Divorce? And I told her this.

My guess is, she wants to have her cake and eat it too. Fuck other guys and keep me around for husband stuff (I'm pretty handy, done a ton of housework/remodel plus trash/yard/etc.). And that shes "not quite ready to put the nail in the coffin yet."

Are there any benefits to a separation? Seems like others have suggested there are but I don't see any...

2. A common refrain here is "DON'T LEAVE THE HOUSE!" Well, she had purchased this house before we met. I've helped pay the mortgage, fix things, etc. Doesn't seem like I have much recourse here though since it's her name on the deed. Is this advice simply for psychological purposes? "Whoever leaves lost the war" type of deal? And if you've got some strategies for how I can possibly pull that off, I'm all ears.

OK, now for the stuff about me...

Background: Lifelong Beta (dad died at 6, raised by mom, she's overbearing, basically NMMNG shit) with some Alpha traits. I've been divorced once before, 5 yrs ago (no kids, assets, was easy). Became familiar with PUA in early 20s, been through constant cycles of LTRs and spinning plates.

Current Marriage: I'm 33, she's 30. Daughter 1.5 yrs. Together for 3 yrs, married for almost 2. She got pregnant while we were dating, manned up (so I thought) and dropped all my plates and married her. Gained weight, became Betaized to the max, stopped doing the things I did to get her. Things went downhill.

At my peak beta-ness, after a dead bedroom and suspecting she was cheating, I did some snooping. Found her journal, read how she was disgusted with me, called me fat, lazy, a momma' s boy, just mean stuff. I didn't tell her I read it, but I got severely pissed. And honestly it was best thing to happen to me.

I took stock of my life. I was messy. Had projects around the house I didn't finish. I was indeed fat. Came to grips with the fact that I'm an alcoholic (after yrs of denial). Realized I had become a pushover, letting her have her way and buying her things (she's a SAHM) while I wasn't getting mine. I was very likely depressed even though I would gave denied it then. I was just coasting through life. No wonder she hated me.

Found Stoicism. Helped with my anger and depression. Went back to keto dieting and dropped some lbs. Messed around with some weights (been messing around for a decade lol) but no serious lifting. We would go to the gym together and I'd do the elliptical for an our like a loser. Did a couple of her classes with her... just sad.

Couple months pass and things aren't much better. I go to old PUA stuff to refresh my seduction tactics, find MGTOW, RP and viola! There's a MRP!

Been implementing MRP since July. Things got better for a while. She even initiated sex a couple times. But then things died again.

Sunday night she wanted to talk. Said she was unhappy. Noted my changes. She was impressed with my weight loss and changes in my body. Noticed that I had cut back a lot on my drinking. But she wasn't happy for 2 reasons:

1. She said I'm too flirty. Probably my fault for reading up on Dread Game lol. I am flirty and need to turn off some of the tactics when I'm with the wife around other women. Owned my shit, agreed that a couple times I was disrespectful.

2. She brought up a situation from when my daughter was born where she thought I took my mom's side over her WRT the baby. Actually read about this in the journal too. And it's Been an issue with her that flares up every so often. It's a grudge and she can't let it go. So Sunday I tell her to drop it. I'm not dealing with it anymore. She supplicates, we agree to move on and work on our marriage.

She comes back Monday while I'm at work and brings it up again. I text her back saying I won't entertain it one bit. She gives me the silent treatment for 2 days, I use the Bratty Little Sister defense. "You're so cute when you're angry," laugh her off, etc. Go lift, etc. She starts showing cracks in the armor this morning, actually speaking first. Starts texting me about an event we are planning this weekend at our house. I tell her to cancel it since we aren't communicating so can't plan/host a party under those circumstances. She tries to start an argument. I keep it playful. She says she is planning to separate. I said get the Divorce. She said no. I said that I'll get it then. And here we are...

Sidebar: Finished NMMNG minus some of the exercises, esp. the ones to share with wife. Halfway through MMSLP, though might put it down now lol. Read all of RM Yr 1, half of yr 2. Read a bunch of MRP, TRP, Hartiste, etc. 4 episodes of Black Philip Show. Started lifting regularly using GSLP. Dropped more weight. I'm 5'6", started at 230 and I'm down to 195. Goal is 175 at 10-12%. Calculated I should get there by Spring.
