Me too. Together for 12 years. Great dad, lovely man, but been unhappy on and off for several years, mostly with physical side, and definitely gone downhill in last 2 years.
Sex big issue. He has no interest in sex and it's pretty much been over since we had our DD 3 years ago. I can count on one hand the number of times it's happened in last 18-24 months. I thought it was something I could live with, as he is a great guy and i do care deeply for him. He ticks so many boxes - kind, good job, trustworthy etc. But I miss wanting it, as well as doing it!
I am also in charge of everything and am the only one who tries to improve things. I endlessly plan, book, suggest etc - date nights / holidays / dinner with tv off / talking / family times. I plan everything for our daughter. I manage all life admin, finance stuff, life to do lists. Things only happen after I write it down, remind, nag, shout, cry and totally lose it. It improves for a bit, then goes back again. I'm now starting to be mean, because I'm so full of anger and resentment. He has no get up and go or drive and will put up with anything for an easy life- it's infuriating and unattractive. The weird thing is, he's successful at work and so must be able to manage shit and be proactive. Which is even more infuriating!
We're going to try counselling, because I've realised I need to move it on. Don't think I can stay in a relationship with zero romance/ sex/ intimacy/ excitement for the rest of my life and keep going through this pattern of nagging and blowing up. Feel hugely guilty for even contemplating leaving an ultimately very decent man, just because of this though. My DD adores him and I can't bear to hurt her, or even him. Also scared I'll look back and think I was stupid and should ignore physical relationship as a trade off, since he works and does his fair share of housework and childcare and maybe I'm a selfish, greedy, awful person
