Bit of backstory, have been with DP over 4 years and have a baby who is 9months. DP has history of depression (by his own admission) but has never sought help from the gp. He also has issues with alcohol and is probably a functioning alcoholic. Again, he knows he has issues with alcohol but refuses to get help although he has tried to cut down. On the whole he's a kind, loving partner and DD adores him. However since she has been born there have been a few occasions were he has spoken (whilst drunk) about not being sure if he loves me and doesn't know if he's only with me due to DD. After speaking through his feelings he admitted that he thinks he's actually just unhappy in himself rather than me specifically. Yesterday he was in bad form and suddenly blurted out last night that he was unhappy with me/us and has been for some time. I asked him did he still find me attractive and he replied that although he finds me attractive he doesn't really fancy me and doesn't particularly enjoy intimacy. This absolutely crushed me particularly as I'm slightly underweight at the min due to health issues stemming from pregnancy (for context I'm just over 5ft and 6stone10). He made reference about my weight being a turn off. He went on to say that he's unsure if he loves me and doesn't know if he's only with me because of DD. He couldn't explain/pinpoint why he was unsatisfied with me/us. We rarely argue and generally rub along well together, which he agreed with. I spoke with him and said I felt that the issue is him being unhappy in himself but rather than facing up to it and his drinking, it's easier to blame me for his own discontentment. He said it's possible but he thinks the issue is me, although really couldn't explain why.
I know people will advise me to LTB , but for a number of reasons that is not possible at this moment in time. My question is, has anyone else experienced similar? I'm starting to wonder if I am actually making him unhappy although he had issues with alcohol long before he met me. Has anyone else had a partner/dh "go off them" due to depression? Just to add, there is definitely no OW on the scene as I know that's a favourite conclusion on MN!
