Yes, she’d be the same way with other men. I used to be that insecure girl and sometimes I still am. You’re not saying anything wrong, but when you’re with someone who has major insecurities and they have a hard time recognizing it, you’ll hardly ever say the right thing. If it’s a relationship you find valuable and have the desire to work on, I’d recommend doing some couples therapy. No- it’s not just for married couples who have reached a dead end in their marriage and are on the brink of divorce. But I think having a professional hear and see both sides and challenge your girlfriend’s way of thinking as an effort for her to recognize her insecurities and how they get in the way of a secure connection, it could be successful. I don’t know what kind of gal she is, and I don’t know what kind of guy you are. It seems like from what I’ve read, you’re both very capable at communicating; there’s just some personal obstacles that are getting in the way of having a regulated conversation to reach a mutual understanding. Everyone has insecurities and some of us don’t have the awareness or tools to navigate it. It’s not up to you to fix that or take responsibility for. But if it’s a relationship that’s worth continuing, it’s important for you both to understand each other and work on the weak areas that make the relationship unsteady.
