TRP/MRP is all still fairly new to me.

I just want to know what was she doing/thinking and how do I better prepare myself so as to not fall for this again.

So Friday night my wife and I are in bed cuddling. She says she's on her period and isn't feeling the greatest so no sex tonight. Ok cool whatever. But that's no reason to not give me some attention so I put her hands on my dick and she's enjoying holding it etc. Then we end up grinding/dry humping each other and she says 'stop you're making me horny' followed by reminding me that she had a migraine and really isn't feeling the best.

So I'm thinking cool maybe tomorrow night she'll be feeling better and will be up for it. Fast fwd to sat night and we're both naked in bed cuddling. She then tells me she doesn't want to have sex until I show her some more intimacy and love (our marriage has been on the rocks and we came very close to separating a few weeks ago)

However since agreeing to try work on things one more time, she will tell me she loves me a few times a day and we have generally been doing better.

So what is the go with one night wanting to have sex and the next holding back??

Is she just thinking 'if I give him what he wants now, I won't get what I want'?

She wants more attention from me and wants me to initiate dates with her. My mind is on our bills and my business.
