Anyway, reconnecting... it's something to talk about together- getting to know each other again as a couple, as a family. How are the kids doing with dad home all the time?
Take it easy. Cut each other slack, hug each other, understand that you are facing this difficult task of reconnecting but do so with love and patience (and with some good days out as a family, as a couple, you can do this). I hope you can find peace again in your marriage.
There really is always the possibility that maybe you've outgrown him. Maybe his presence in the home isn't a positive one for you and he's picking up on that. Just a thought. But sometimes, time calls time on a marriage and it's very sad but something that can't be reversed. I hope that's not the case, but it's ok to explore that possibility too.
I think what @TheVanguardSix wrote is beautiful and empathetic. @ScatteredMama82 Go easy on yourself and your DH. Be kind and realistic with each other. You are going through changes and transitioning from a long distance relationship to living together full time. It is a readjustment for both of you.
Also, when you posted that you think that he wants you to be the same as you were when you were younger before you had kids, have you asked him if that is what he expects of you? That needs to be addressed.
If he reassures you that he does not expect that of you then you can have peace of mind about that issue. If he says that he does have that expectation of you then that is not ok or reasonable and you will have to address that.
