Most Helpful Guy
He says he doesn't know what he wants, he knows he wants me in his life, and he THINKS he just wants to be my friend"
You are a convenience. He wants you in his life...But doesn't. He wants you there when he wants. He wants to have you around to have fun with (not sex). But still have the ability to test the waters with others. Then if that doesn't work...Guess who he turns to?
He is using you. And as long as you're available he will continue to use you. Once you find another relationship, you're no longer available at his every whim. So bye bye.
If he doesn't know how he wants you in his life right now he needs to shit or get off the pot. Grow up and make a decision. Either you're friends, lovers or nothing. A decision has to be made.
