Start of the school year, I met a girl she and I have hit if off very strong since that day but till now she had a boyfriend, but up until two weeks ago they broke up, and now all her attention is focused on me, but I keep feeling as if these emotions are a bit forced, Is she really into it or am I just a rebound?

Go with your gut, I'd venture you might be a rebound. It seems like she is just shifting her attention to you.

Was she still giving you attention when she was dating this other guy?

Yes actually

Yes Carrot, she did

What are you looking to get out of this situation?
