I'm so confused

I'm so confused right now b/c I really like this guy and we went out but he moved away and I never get to talk to him or see him...but i still like him, but now, theres this guy that makes me happy and I have a crush on him and he's really cute and sweet but we don't go out. I'm scared if we do go out then I won't be able to let go of the guy that moved away. What should I do?
