Thanks Sugahorse, I think you are right in saying she is still finding herself - I'm not sure how new her diagnosis is?
I had an insightful conversation with her about an hour ago. She opened up to me more than I thought she might. I asked her how she was - and she said she felt awful. She said that she really like me, but KNEW that she was going to hurt me, because of how she is feeling right now. She said she hates it but is aware of whats going on and she wants to protect me which is why she's told me that she might not contact me for while. She then disclosed that she slept with her ex girlfriend last weekend and that the possibility of it happening again this weekend, is strong. Her ex girlfriend also has bipolar - I can't imagine what that combination is like?!! Her ex is leaving for Australia for 3months this weekend and as she put it 'will be out of my hair and give me time to myself'... apparently they just go back and forth hurting each other. Not healthy

She asked me what I thought? I said i cared about her, i really like her and I can understand that her relationship with her ex has little boundaries, but yes, that it made me feel uncomfortable and that I didn't want to lie about that.
Im tempted to let this weekend pass and see what happens with us. I know its going to screw me up knowing that her ex is there, and that she's feeling manic..Im moving house this weekend too

I want us to have something, but Im scared now. What I want to say is for her not to panic about having feelings for her ex and acting on them - but I know that saying that, I'm putting myself down! in a way and just allowing her to do what she wants... but Im not sure how to handle it. Is this her being manic? or is this her?
I don't know whether to suggest we just spend some time together, like going for a meal, cinema, walks etc and see what happens?
