It makes sense for you to be apprehensive about getting involved with a man who likely also has attachment issues, knowing you also do. It’s good to be self protective and have eyes wide open.
Ideally, you want to have a relationship with someone who has healthy attachment. It is possible for you to have a healthy relationship with someone who is capable. I have read a person without healthy attachment can have a healthy relationship with someone who has healthy attachment. It is when two people do not have healthy attachment that the relationship is definitely not going to be healthy. But I am not an expert, just someone who has read up on this for myself with these issues.
