Thank you for reminding me why it is awesome to be single!
My ex always got to go on his reenactment trips whenever he wanted (didn't ask, just informed me of the dates he'd be gone). It was rare, especially once we were married, that I had solo things I could do without him tagging along and guilting me if he wasn't included enough. So I get it. And honestly, I enjoyed my alone time while he was gone, even when we were married (but of course, more now that we're divorced).
I'm on your side on this one because quantity doesn't always mean quality couple time anyway. If when you come back the three of you do something special (like go get ice cream, or have a nice dinner, or see a movie together, whatever), that is a bigger win than just sitting around the house doing nothing, but breathing the same oxygen. And the threat of withholding sex as punishment is a bit of an eye roll to me. Don't you both suffer if you don't feed your intimate life? That's not a reward, it's just part of a healthy connection. But I digress.
You've been upfront. And it's healthy to do solo things sometimes, have his friends/her friends/our friends, and they all don't have to fit in all three categories. You're not married, but I believe that would be the case even if you were. Happiness comes from within, right? We've learned this. You don't have to be each others' everything. So she has more alone time with her daughter to do special things, just the two of them, and you have your afternoon that you want, too.
When those red flags come up that remind you of the past, heed them. Don't repeat that past toxicity.
