<human>: I've been in two relationships so far and both were emotionally abusive in some form or another. The first lasted four years and he attempted to control my every move. The second was verbally abusive towards me and temperamental. This last one ended over seven months ago. 
Since then, I've taken the time to work on myself and improve my life. I'm much happier for it but I've realized I am saddled with these trust issues towards men. I recently met a guy and though we've known each other for two months and he's been very open with me, I am very withdrawn from him. I don't trust what he tells me even though he has proven to be very genuine and understanding. I always have these doubts in the back of my mind that somehow he's going to fuck me over if I let him too close. This has pretty much caused me to cut contact with him in a desire to keep myself safe. 
I don't want to be like this, but I don't know how to let my guard down. This lack of trust isn't even really recent as I was distrustful of my first boyfriend halfway through our relationship. I don't want this to become a pattern as I'd like to one day have a healthy relationship. Is there anything I can do to break this pattern of thought or at least tone it down a little?

Can you condense the text into a few key points?
<bot>: History of abusive relationships has caused me to be withdrawn and unnecessarily suspicious of guys. I don't want this to continue but I don't know how to fix it.
