You think so? I know she said she wanted a lasting relationship with me. Marriage, kids, home and all that. And the weird thing is she was even willing to cut ties with that guy she was speaking to. She kinda confused me in that at first she called him a best friend then the second time I brought him up she thought of him as like a brother. So I didn't know what to think?
Like how sure are women when they call someone a brother yet have slept with that person in the past? I don't know too much for my thick skull to handle.
But either way the relationship was destined to fail because I just can't right now with my mental state.
Well, you said the last relationship you were in (with her) took a toll on you to the point where you were drinking every night to keep things interesting with your gf. Truly happy people don't feel the need to drink every night, unless you were drinking in moderation. So something must've triggered your drinking.
You also mentioned that she had a lot of partners in her past, so do you mean she was sleeping around a lot?
In my opinion it was rather disrespectful of her to still be talking to a guy that she'd slept with while in a relationship with you (especially if your relationship was relatively fresh.) If she had discussed with you before getting involved with you that she has an ex and that they've remained friends since forever (but no more sexual attraction), then maybe I'd be a bit more forgiving.
How long ago had she been in a sexual relationship with this guy before she got with you? If it was a long time ago I'd give her the benefit of the doubt, but if it was recent she may have still been on the rebound and keeping her options open in case things didn't work out with you.
As for being "brotherly" or "best friends" with an ex, it's entirely possible. I lost attraction to an ex and wanted to remain friends with him but he didn't want to. I know quite a few people who've been platonic friends with their exes for years.
