Pretty much i liked this girl in uni who had a boyfriend, we hanged around for bit in the first few weeks, but she found out that i liked and we didn't speak for months. i moved onto other girls and now shes broken up with her boyfriend who came round for some reason after they broke up to help her with her coursework a day before valentines even though he doesn't go to any uni, she told me he was sleeping on the floor for some reason this was the first thing she said to me in like months.

now shes hanging round my room and checking up how i'm doing some times and were talking allot more.

I still like her but don't really know how to approach this without being a rebound and not going into the friend zone by talking about her boyfriend which she keeps trying to bring up.

If she keeps bringing him up, you really need to keep your distance for awhile until she's over him. Otherwise you're pretty much guaranteed to get friend zoned. When you're forced to interact with her and she brings him up in conversation, try to change the subject quickly.

yeah i told her i didn't want to speak about him cause she kept on getting upset, but that was before we didn't speak but shes trying to speak about it i just change the conversation.
