I know I will probabluy get raked over the coals for this, but I just want to point out a few things:

1. you are only 21
2. you've only been "hooking up" for 3 months
3. he doesn't have any other friends in the area

It is possible that he needs you, where you both are right this minute, because you are comfortable, safe and familiar. I would (in agreement with nearly all other post-ers) encourage you to let him go. There's no telling what is in store for him at home, let alone you and your baby.

Whatever possessed him to say that he "wasn't the guy for you" may have something to do with whatever is waiting for him back home. Let him go, get settled, and contact you if he wants.

In the mean time, buy some erotic literature and a vibrator and "set yourself free"!
