Have to agree with all the ladies above about raising kids being exhausted. Yes, give her space and time but you should force the kiss goodbye and hello. Also, holding her hand, in the car, while going to sleep and maybe ask her if you can just cuddle with out pushing it to sex. People need contact. She may want a back rub but doesn't want to go there because she doesn't have the energy for sex. I know you don't want to have the real conversation but you need to. Communication is key. Do go to counseling, you said the two of you talked about it and your relationship is ABSOLUTELY worth it.
Married for 22 years, together 25 yrs, 2 children
