<human>: Summarize the given text in a few sentences.

Basically I worry about me and my girlfriend more often than I'm actually enjoying our relationship, (12 months).
I don't really know where to start, I think the problem is that I don't trust her. 

I want to, and I try to trust her, however I'm always kind of expecting the worst. For example whenever she goes out for drinks there's always the thought that "This might be the night you get cheated on and dumped".
She's never actually done anything to deserve these feelings, she's always been honest and open about things whenever I ask.

I've told her a few times that I sometimes have a hard time trusting people, but I feel like if I'd tell her everytime I'm feeling anxious or worried she'd eventually get sick of it and dump me anyway.
We did talk about this once, and we agreed that I should tell her when I'm feeling like this, but lately I feel she's starting to get tired of me telling her all the time and asking for details when I'm not with her, and the last two times its ended up with us arguing instead of it helping.

She's never felt like this she says, and when I asked her she told me she's "not the jealous type" and that she geniunely trusts me. This makes me feel ten times worse about myself, like there's something wrong with me. I don't want to be the one always worrying..
<bot>: I don't want to live a life of anxiousness and worry by keeping my feelings bottled up inside, but I don't want to drive her away by bothering her with my trust issues all the time.
