Is your boyfriend 9 years old? Leave him in his mommy's basement and try dating an actual adult. He's got some issues, I'd take this a sign to get the hell out before it's too late.

Like everyone else above, I agree that your next boyfriend should be an adult.

9 times out of 10 he's nervous

Give him a choice- live together, get married or goodbye. Personally I'd suggest goodbye. If he's a mamas boy now he'll always be a mamas boy.

Graduated your master's what?

If mommy comes first, you will always be 2nd.

hey if he wants to pass up on a girl who got her masters hes an idiot feel free to pm me xD

He's scared, which is normal and maybe he just needs some time or some talking. It could be the case he does want to back out of it, so in any case you just talk openly about what each of you want. It's always better to know the real truth than to comfort yourself with illusions or even worse torture yourself with fears.

Momma's boy....

Get out of that "relationship" now. I can only assume the both of you are at least in your mid-20's, and yet he is still worried about what his mother thinks in regards to him making his own grown-up choices. It won't change. Believe me, it won't.
