talking to my crush

So I've finally started talking to my crush but things are hard to read. He apparently has had bad relationships but I don't know in what ways yet. He hasn't gotten that personal. It's just that he clearly has trust issues and is afraid to get into something new without jumping to conclusions that he is seeing negative signs or red flags about me when I have never done anything wrong. I dont flirt or talk to other guys but he has even said that we aren't anything to each other yet for other purposes. It just seems like one hell of a time trying to be a women in his life when he has such a barrier up.
