boy problems

Lexi
Hey so I'm a freshman in college, and my first night here I met this guy who I made out with. He got my snapchat and we started snapping everyday. Turns out he's totally awesome and I caught feels. I was worried he only wanted to sleep with me, so I talked to him and he said he isn't that kind of guy. But sometimes he opens my snap and doesn't respond for long periods of time, and I'm always the one to pick the conversation back up. He claims he's super busy, and tells me not to overthink it but I don't know girls, I feel like he's not really into me! What do you guys think?
