<human>: We've been together for about 9 months. We worked together for some time and became friends. Eventually more than that. Soon afterwards she told me some heavy things. She has had problems with sexual and physical abuse in the past. She has some strong anxiety problems (probably stemming from the past but I'm no psychoanalyst). These manifest in occasional anxiety episodes and slightly manic behavior. I've managed to work through it and be supportive. After all, no one is perfect. She came into my life after a difficult time with another girl and she has been nothing but caring and supportive of me since. No jealousy, no drama. The problem now is that I know she cares so much for me and I don't think I can give it back. I'm worried about her mental health and I don't want to break her heart (Which is ironic because she swore she'd break mine when we first started). It doesn't help that it's her birthday tomorrow, the holidays are soon, and her parents are getting a divorce. I've been able to blame my increased distance between us on college finals and other stresses, and I know she's concerned about me. Another problem is our sex life. She's a bit more, ah, voracious than I am. I use to be able to keep up but I don't think I can keep at her pace. I don't see us lasting and I even went into the relationship knowing it would be temporary. What's worse is that I've been thinking about my ex a lot. We dating for a long time, moved across the country together, kind of broke up, and had an on and off relationship as we adjusted to our new lives as "adults". One day, the ex stopped talking to me. Months passed and then we ran into each on campus the other day. We're having coffee tomorrow (to catch up, we were good friends and I genuinely want to know how she's doing). I'm trying my best to not think too much on it and try to remember why we broke up but man, there are things I miss...

Can you condense the text into three sentences or less?
<bot>: My gf loves me a whole lot, I don't want to break her heart, the timing is bad, she's slightly unstable, and I'm meeting my ex for coffee tomorrow.
