Need Help Please!!!! Its About A Guy.

Hey y'all,

OK here it is.
I met this guy a little over a year ago. We started dating and I love it but we broke up because he wants to get married soon but I don't. I'm only 18 he's 22. And we've been off and on since then. Monday we went to his parents place (they have over 10 acres of land) we laid out in the yard under the stars (his parents weren't home) and he asked me if I was falling for him and I thought about it and told him I may be and I asked him the same question he said he thinks so. The next day I texted him and told him that I'd had really been thinking about what we talked about yesterday and that I was falling for him hard and he said that he did think there was something there but he didn't want a girlfriend right now and that he didn't want any kind of relationship and then he went on and said that he didn't want to hang out, see each other, or anything till he gets his head on straight.

I don't know what to do. This is the first time I've ever felt like this about someone.
