TOTALLY CONFUSED : ( What to do about the guy I'm dating?

Soooo, I've been single for a while now. I'll say about 6 months due to the fact that I've had a really troubled past when it came to guys. So there was a lot of trust issues regardless if I knew the guy or just meeting them. Until abouut a month ago I started a new job. I wasn't looking for anyone new in my life but this guy I wouldn't normally be attracted to starting pursueing me in his own lil way. Showing some attention but not too much which I'm not use to because guys are always showing me attention. But anyways I became instrested in him & we became friends & eventually began talking. Surprisingly I began to trust him & actually fell for him. So now we are having some problems now that I'm attached. Me being a female & have alreadly experienced the feeling of hurt I just want everything. To be right between us so I tend to nag & complain about things he doesn't do or etc. So he hates that I get mad about things, or he gets mad at some things I say & sometimes flip my words. So now we're at the point that he gets mad at every little thing & will totally ignore me until he's ready to talk. He also has a problem with saying things outta anger. Our disagreements dnt last long only about a day or so but what my question is how do I make things better between us. O yea he has never been in love or trusted a girl. He's a year younger than me. We have so much in common so much, & when we are together its so fun. Help!
