i personally dont think that "talking" to someone is a good idea. it usually never leads to anything good .... and its just a cop out for either person to hook up with other people, too. -- because you know half the time you arent really exclusive when your "talking".
WVU Alpha Phi - you should just let him go. he sounds like hes not that good of a guy if hes pinning things on you. theres plenty of other BETTER guys out there that wont play head games with you, and you deserve it!
so - just stop thinking you did something wrong, and stop thinking of how you can save you and him - and find a neeeew guy
im sure it'll be worth it once you find someone else!!!
