Being the rebound boyfriend is never an easy task, and lots of times you end up ****ed over yourself.
Date her, love her, enjoy it...but wait a few months before you let her really get under your skin. Its hard when you've been after a certain someone for a long time and then the availability comes up so suddenly like that...but girls on the rebound tend to use guys.
Its not ALWAYS that way, but I don't wanna see a bro of mine get hurt like I did. You'll recover, but you'll be wiser. If you can hear it from me and not have to experience it that'd be great.
