I don't want to believe that she's going... Do You?

Me and this girl have been talking for about 6 weeks now and i really like her alot. She says she really like me alot too. Since after 2 weeks we met, we've been spending alot of time together and we have had ual intercouse multiple times, and I could tell she enjoys it alot. Two days ago her ex boifriend calls her and wanting her to come to ATL to see him, but she told him about me and I know she doesn't get back with Ex's nor have anything to do with them. but yesterday she keeps throwing it up in my face that she will be going to ATL next weekend to see her ex. This morning she's telling me that she might go and party it up in ATL next weekend. She's just saying it too much that I'm beginning to think that she's serious. I don't know but she might be saying it to make me jealous. I don't know what to think anyway. Do you think she will?
