Will things turn around between us or should I just give up hope?

I recently became un-engaged, not my choice at all, and I don't really know what to make out of the situation. I really do love the guy I was with obviously I figured he was the one, and a large part of me still does. We had dated in high school, and then broke up and after not talking for two years we started to again and then started dating and then we got engaged, we went through some pretty interesting times like him getting a DUI, then a suspension for driving with no license and then him going to jail for a bit because of it and losing his license until next year, and being broke and having to move. I also moved to his hometown with him because he wanted to be closer to his friends, and so I agreed wholeheartedly and we moved up there. Then he got a new job, where he would be away for six months with only one day off and two days after he left for work he said that he needed to sort his life out and that he couldn't do that with someone, how I have a good life and he would only wreck it and that we moved to fast. I told him we didn't have to be engaged and could just be together, and that I didn't for a second think he was going to wreck my life which I don't, and he said he still loves me. Everyone thinks I am crazy for still loving him, and for still wanting him but they don't understand the relationship but I am not really sure what to make of the situation and I am wondering if anyone has advice, or if they think the situation could turn around. A guys opinion would be really helpful as well.
