Pisces Man Defensive

I have been seeing a Pisces man for 7 months now and recently I have been stalked by someone else that I dated and also had my identity stolen by a relative. Both situations have caused me to question my trustworthiness in those that I consider close to me. This prompted me to look into this Pisces man whom I care for greatly, a bit more. I found that he was not forthcoming about other children he fathered. I’ve wlways been honest with him and I told him what I did and why and he immediately became defensive and dismissive. I don’t feel bad for my actions considering recent events but I wonder what to expect from this man. He would not respond when I suggested ending communication multiple times but I now question what else he may be hiding and if he will come clean to attempt to repair this. Any thoughts?
