<human>: I have had some past experiences in relationships that have left me with some trust issues, as well as my past experiences with men with girlfriends flirting with me and my family's long history of cheating husbands that has left me very defensive about men in general. I told him about this when we first started dating, and yesterday I brought it up again because I had obsessive thoughts that just wouldn't go away and I needed to rant about it to calm me down. 

He told me that he is not planning on hurting me, he cares about me, but that it is a problem I have to deal with and fix on my own, although he understands if it takes some time. He means well with what he said, but I feel like I'm beating myself up for not trusting him and hearing him say that I have to fix this on my own just made me feel miserable. I'm probably just blowing it out of proportion, but I've been working really hard to be better in this relationship, and it's starting to make me feel exhausted. I know it is something I have to work on, I just feel like there are so many things that I have to work on to be a good girlfriend and I currently feel emotionally, mentally, and physically exhausted.

Summarize the given text in a few sentences.
<bot>: I talked to my boyfriend about trust issues, he brought up that I need to work this out myself. He is right, but I don't know why his answer made me really upset.
