<human>: I'll (24m) try to keep this brief. We met through work and I had strong feelings for her right off the bat. Found out she had a bf so I backed off out of respect but we became really close friends. Two months ago, she broke things off with her bf (her 1st serious relationship) because she's been really unhappy with him for a long time. Also, she ended up catching feelings for me and felt it wasn't fair to continue their relationship. 

She fell into a deep depression but says she wants to take things slow with us and I follow along. I knew she wasn't ready for anything serious but I felt she was worth the wait. Fast forward two months of hanging out and casual dates, she admits she's really falling hard for me. We end up making out for the first time and I felt the sparks fly. Ever since that night, she's been cold and distant. 

Two nights ago, she confesses that she thinks she's getting back together with her ex. She tells me that after fooling around, she "felt things weren't quite right with me and she doesn't see us in that way afterwards." That she's even more depressed now without him. She stresses that I wasn't just a rebound and her strong feelings for me were genuine but I'm still hurt.

Is her depression clouding her judgement? Is one night of making out really enough to know if someone isn't right for you? Was kissing someone else too much of a change for her? Or was I just the rebound she needed to realize she really wants him back?

Give me a shortened version of the text
<bot>: She's coming out of a long term relationship and wants to take things slow. Nothing physical. Sparks fly and we're falling hard for each other. We finally fool around after 2 months and she jumps ship.
