Do you think this is a good plan?

Ok so I broke up with my ex in May and had two rebounds since then. I got too attached both times and got slightly hurt when the first one ended and really hurt when the second one ended. So I'm going back to college in September so I figure given the cirstance I'll spend the rest of the summer not getting involved with girls and then when I get back to school I'll play the field and have casual fun and after doing that for awhile (2 - 4 months) I'll start looking (cautiously) for a new gf. Hows that sound?
