Rushing into marriage

Last year I met this amazing man who was vacationing in my city. The thing is he lives in Northern Ireland and I live in Orlando. It’s been a year and he’s mentioned marriage and kids which are great but I feel that he’s rushing into everything. I’m currently a 23 year old college student and I’m no where near his level of success just yet. I’m not even close to being finished with school.He on the other hand is 27 and a lawyer. Part of me feels slightly intimidated by that but also a part of me feels suspicious because why would he want to date someone like me who isn’t on his level? On top of that he’s in such a hurry to get married. First of all, I don’t have that great of a personality for him to be head over heels like that. At first I thought maybe it could be for a visa but he wants me to eventually move to N.Ireland which also scares but excites me. I’ve questioned his motive a few times but I feel that I have such a wall to protect myself although he has proven to be a stand up guy. What are you opinions on this?
