I have been dating a girl that I really like for about 6 months now and it is going great. But my ex girlfriend and I have started talking again, and I think I am starting to fall for her again. I went over to her house yesterday for a little while, and nothing bad happened, but we were flirting alot, like we did when we were together. I know that I would never ever cheat on anybody, but like I said I think I am starting to fall for my ex again, but I really really like the girl I am with right now. What should I do? Someone please help!
