My ex used to be jealous of my T but just because I wouldn't tell him everything we talked about. I feel more comfortable having a male T and that made him uncomfortable. He kept asking to go with me even though we didn't have any specific couples issues that could be worked out there. After a while it proved too much for him. My current bf has his own T and recognizes how different that relationship is from everyone else. So if I go to a counselor on campus or something he understands, luckily.
