Need help. Confused by a guy, long story sorry?

I have been seeing this guy for 3 months on and off. We are currently on, and I told him I need some kind of commitment from him, as in an exclusive relationship. He told me he likes me alot and thinks I am beautiful, and said how much I make him laugh and how he loves that I never say nasty things about anyone which is why he likes me so much. But then, he said he is thinking more long term, in the future, and can't see himself marrying me. His main reason is coz he says he wants to go overseas once he has finished his diesel fitting trade for like 2 years. I was so hurt, he seems genuine about his reason, I guess ppl can't help the way they feel. He is only 22 and I am 24, I guess he really is just a young boy and wants to have fun. Even he agreed when I told him this, then we were laying in bed, and was staring at me saying how much he knows he is going to regret his decision coz he has done so before, then he blurted out "why can't you just get pregnant?" and I was like "what!?" and he was like "then I would be forced to grow up and stop being an indecisive boy, coz I have turned other girls away for the exact reason and always regretted it".... do you think he is just mind f****ing me? Should I just get rid of him?
