Hhmm yeah now when you share more details it looks like there is more to it than her going out with women. I think that’s what happens when details aren’t provided (not like it’s possible to share everything, I get it). But if you said she goes to bars dancing with men and women and doesn’t invite you, I’d have a different thought about it. I thought more of like I go with my girlfriends places. On Sunday while my husband was in finally opened gym I went with girlfriends exercise walking in a park and then breakfast at a dinner, my athletic clothes is probably on a tight side (revealing?) for comfort but I sure don’t have body dysmorphia or was there to get men to look at me hahaha Now what you described is different
Going dancing at the bar with a group of males and females is quite different than going out with girlfriends. It sounds that she didn’t want you there. It sucks. I’d be very offended if my husband went dancing with other women without me. I can’t even imagine. It’s not the same as going to meet with his buddies to play soccer at a day time (example)
I’d not blame single women for “taking” her anywhere. Most of my girlfriends are actually single as widowed or divorced or never married but they can’t “take” me anywhere where I don’t want to go. I for example don’t drink like at all and neither do they and I don’t go dancing, well neither do they but if they asked me to join them at bars for drinking purpose, I’d not go. Your wife has a free will. She goes because she wants to. She is an adult and can’t be taken places.
Honestly I am not sure if this situation will ever improve as she doesn’t seem the right woman for you. Sometimes people are just wrong for us. I was in a relationship with someone who drank, I thought I could change him. Silly me. Solution wasn’t to get drunks to stop drinking. Solution was to go for people who don’t drink. I am long gone and am married (to someone who doesn’t do any substances) but that previous person still drinks.
What do you get out of this marriage? Is there any positive side to it? It sounds very unhappy for me. I am sorry

You’d be much happier with a different type of woman
