So i've been dating my girlfriend for 14 months now and am having questions about it. We are both around 18 and i recently gave her a promise ring. I still love her to death and she recently went on a trip for a week with very little communication between us and i miss her really really bad. The bad thing is that i always seem to get mad over her for stupid things and i make myself more mad than anything. this has been happening for the last couple of months and it has made her believe that every little bad thing i get upset with which makes me feel even worse.

Also, all i ever want to do is dirty things whenever shes around and she really isn't like that. Her parents are really strict and they don't like me. They have no reason to not like me they just don't.

Any help on how to help my relationship and how to get her parents to like me would be great.
