Well, I'm in an open relationship, so sometimes I occasionally hook up with different people (usually a threesome, a lot of time I'm not comfortable meeting up with someone when I'm alone). Last night I was talking to a kinda-ex-girlfriend (It's complicated >.< ) and we strated talking about the idea of getting together sometime. But I worry: She seems to be getting emotionally attached, and I have a boyfriend who I care a whole lot about. It's hard for me to make it clear to her that I'm not willing to give him up for her, she's emotionally unstable and has been in and out of mental institutions, a couple times for breakdowns, and once most recently for attempted suicide. I'm very worried about her, and she tells me she's lonely, so I wanted to keep her company and give her something to feel good about. She has a negative self image and I think she needs to be told that she's beautiful, so I tell her. But like I said, she's emotionally needy. I'm kind of stressed out because I need to be there for her, but still establish boundaries. Any suggestions on what I should do???
