She thinks I don't trust her.. what do I do now?

okay so the past few weeks, me and my girlfriend haven't been getting along the greatest. she thinks I don't trust her. and she thinks all I want is sex and that deep down inside I really don't care about her. but I do care about her a lot.

we had made plans to get together new years eve. she was on vacation with her family for a week in Wisconsin. she got back new years eve day,and told me she was too tired to do anything that night because her flight didn't get in until 4 am. she's been blowing me off lately , just a couple of times.. and I was kind of p*ssed about it because it was new years eve and all..and I hadn't seen her in like 10 days. I told her she would end up going out anyway, and that she could sneak out and see me if she really wanted to . I was just saying dumb remarks at the time because I was kind of upset and I had a bad day at work. so now she thinks I question her about everything and that I don't trust her. which in a in a way makes sense because I do sometimes question her about stupid things . cause we don't see each other very often .. just a couple times a week. but look .

ii love this girl . she's everything to me. and I need to make this better between us. how can I show her that I trust her and that I really care about her before its too late? I call her and she doesn't answer her phone.. I talk to her on Facebook , but she won't say much ... just kinda ignores me. what should I do? it may be too late. I don't know . she I asked her to hangout last night and she said "idk just give me some time" so what do I do in this situation? I've never dealt with this before..
