To keep a long story short (ish) - DH and I got married last year after 3 years together and are quite well-matched in some ways but have now drifted so far apart that I'm considering divorce. A few things have cropped up or gotten worse since the wedding, like his need to be left alone and not do anything after work (and yet he wants to have a child!), treating me like a housemate - we both have quite low sex drives but he's literally always too tired and doesn't show any affection which doesn't make me feel great. Last time we had sex was on our honeymoon. We tried a few months ago; he couldn't get an erection but has not seen a doctor about it. I can't think about spending the rest of my life with someone who doesn't want me that way.
He also refuses to apologise for anything - from little things to big stuff like embarrassing me and being very rude in front of my friend. I am quite a gentle person and probably apologise a little too much but his inability to do it really bothers me.
I feel like he wants to stay with me because he doesn't want to deal with the fallout of telling his family, friends, looking for a new home etc. In all our conversations about the current situation, he hasn't told me he wants to stay because he loves me once. I appreciate that romantic feelings fade in long-term relationships but shouldn't we at least want to be around each other? If this is the rest of our lives now, I feel really sorry for us both.
Sorry for the essay! I guess I'm looking for some opinions on whether falling out of love is reason enough to get a divorce?
