I can't decide

Jayme
So I have been talking with a guy for about 2 months. We aren't super serious but we do really like each other. He's nice to me, but we're really different. Recently a guy from my past came back into my life. Now I am confused and don't know what to do. I feel like the guy from my past could be good together but I don't want to hurt the other. What do I do
