I had a girlfriend who had a guy like that for awhile and ran for the hills when the guy took her to look at houses for him to buy that they were going to live in after they got married! They'd only been dating a short while, like you and this guy.

Follow your instincts. If he's this pushy now he's not going to get any less pushy later! He isn't thinking "right", doesn't know how to relate properly. That's not your problem.
