Sounds like he will sleep with you, and continue sleeping with other girls as well, not into the idea of a relationship. So my advice, don't so it, its someone you like, you'll only hurt yourself more by getting more attached, find another crush. Crushes come and go, plenty of guys out there, Don't waste your time chasing the wrong one.
