Edit; Losing* sorry for the mistake, I rushed through and can't change it.
Hello! I need advice about my relationship. Just a little context. My husband(36m) and I(35f) have been together for 20 years. We've had seriously rocky times throughout, but always seem to work it out. One thing that has never suffered is our sex life. At least 2/3 times a week even if we weren't in the best shape in the relationship. Last year, I confronted him on some lies involving his coworker (51f) whom he's been close to for years (its always bothered me (their relationship) and he knows this but continued the relationship at work. He left me that day. "Next time you hear from me will be through an attorney". After a year of fighting and "working on it ", we decided to give it another go because despite everything, there IS love there as well as 2 daughters. During that year, we had sex a few times and were still intimate. After we decided to stay together, something changed. He won't touch me. After 6 months I finally broke down and asked why. He said he was just stressed or didn't think about it. He said it wasn't me, it was him. We did have sex that day. I thought maybe it had broken the ice and we were going to be ok. We'll, its now been another 3 months. He doesn't even look at me when I'm naked. He doesn't flirt or even seem interested in the least. I've mentioned it a few times (hey, we should have sex soon) (rubbing my booty on him in bed) but I get a "yeah that sounds good " or just some generic response. I feel unattractive. I feel like he doesn't want me anymore. I'm disgusting. And now that I think about it, its ALWAYS been me to initiate it. Has he ever actually wanted me sexually? Whats so wrong with me? I know I'm not the prettiest woman, but I get hit on every so often. I get asked out at bars sometimes. I'm just lost.
AIO or should I be this upset?
TLDR; after 20 years, husband no longer interested in intimacy
