Search Results: getting over an ex boyfriend

I had a boyfriend for a year and a half. We both loved to be goofy together and do anything that could possibly be fun. After I graduated from high school he broke up with me, because he was younger than me. We have been broken up for a year and up until recently have has LITERALLY zero contact with each other. He initiated contact with me recently and we got together and talked for hours and ended up kissing. While we were talking we talked about all of the things we used to do together and more or less took a long walk down memory lane. He spoke jealously, asking me about why I talk to the people who are my snap chat best friends. I could tell that it really upset him that I had been snap chatting guys, because it meant that I was talking to other guys. He also saw other people's names come up on my phone while we were talking and was very jealous that I had ever texted some guys. The next afternoon we were texting and he let me know that he wasn't interested in a relationship right now, because he is focusing on getting into a college athletic program and needs to work on his skills. He suggested we just be friends with benefits... Shortly after this he asked me if I wanted to come over to his grandparents house to meet his brother's new son. I told him I couldn't because I was at the gym. An hour and a half later he asked me again if I'd come see the baby.
I feel like I am getting mixed signals from him. Friends with benefits one second, come hang out with me and my family and meet the new addition the next second. HELP!!!
