Breaking up and rebounding

I have been with my boyfriend for almost 2 years, but I have decided to break up with him next Saturday. This is not easy for me but I’m not in love with him anymore and it will hurt us more to stay together.

I have been ready to be single and spend time focusing on myself, however a couple days ago I met a really nice guy at a party. I’ve been talking to him a lot in a friendly way but I’m worried that once I break up with my bf this guy is going to become a rebound. I’m getting the feeling he likes me but I don’t think it’s right for me to get attached to someone so quickly. This guy doesn’t know anything about my breakup or boyfriend. What should I do?
