Involved with best friend's ex
Okay so I am kind of in a very sticky situation. My best friend and I have been best friends for about 11 years or so and I love her so much, but something has come up that is troublesome and awkward for both of us. Last month or so she tells me that one night when a bunch of my friends and I were hanging out, that her ex-boyfriend of a year and a half was flirting with me. Right off I didn't believe her because her ex and I were pretty good friends since they had been dating. SO I brushed it aside and said that I would never be interested in him. Later on he asks me to hang out and I didn't think of it as a date, but apparently he did and I later on found this out and I said again that I didn't want to date him. Not because I didn't like him, but only because I knew about him and my friend and I would never date him because of her, which I also told her. I didn't want to start getting emotionally involved if it couldn't work. But then my best friend tells me that I should give it try because I could be missing out on something really good and that it wasn't fair to anyone if I did that. She had been telling me this for a couple of weeks before I said that I would give it a try. It should be known at this point that (not that I'm trying to make excuses) that they had been broken up for about 5-6 months and she initiated it and has no feelings for him. Anyway, so now we have been dating for about a month and I really like him a lot. He is just the kind of guy that I have been looking for and as all the qualities that I want in a boyfriend, but now my friend is telling me that she is angry about it and that she probably always will be a little bit. She has another boyfriend now and things are still really good between us, but when she tells me that she feels really angry about it sometimes, I get really confused because she is always changing her mind (which I totally understand). Now the only problem is that I am really emotionally invested in this relationship. Like more than any other relationship I have been in and I really see this going some where important. I never hide anything from her and I always tell her that I love her more than I could love any guy and if she asked me to break up with him I would do it in a heart beat, no matter how much it would hurt, so what should I do this far along the line?
