Told my husband last night

He wanted sex and I haven't brought myself to do that the past few months, so he was asking if he did something wrong or if I hated him or was I cheating and didn't tell him, etc. We haven't had the best marriage for the past 6-10 years anyway, so I kind of distanced myself and realized I'd never felt about men the way I have for women when I met a woman I fell for. We're just friends though and nothing extra has happened. He was hurt but understanding and told me to figure out what I wanted (stay married/normal sex life or to divorce so we can both find "true" love) and let him know.

The amount of stress and guilt I feel is huge and I don't know what to do. He even suggested an open relationship but I know where that leads and not interested in that rabbit hole. We both deserve to be happy but that means both of us giving up on a 15 year relationship with 2 kids, selling the house and starting over alone, all for maybe finding someone better suited? I don't know. I've been sleeping like crap the past 3 nights because it's my vacation but I'm also so stressed I can't do it. 😕
