<human>: Give me the gist of the text in a nutshell

Hey guys so basically I have had a very shitty string of relationships in my life. Ive been cheated on by just about everyone ive dated and It has ruined me to the point of being extremely insecure. Im now dating the women of my dreams who does everything to show me how much she loves me and that she wont hurt me. Even though she does this I cannot for the life of me not think she is always doing something wrong I don't know how to trust because I've never been able to and I don't know how to not be insecure because I've never been shown love like she gives me. I honestly don't think she has cheated on me or even flirted with another guy behind my back but for some reason my mind immediately makes me think she is always doing something bad because im so insecure and have so many trust issues. She knows about all this and even though she continues to reassure me she would never hurt me I just cant wrap my mind around that.
<bot>: have serious trust issues and insecurities with current girlfriend because of past relationships and even though I don't believe she does anything bad I cant help my mind thinking bad things. Any advice would be helpful.
