Would it be a fair to say that you’ve had limited experience in this area? I joke that I’m a weirdo, but I don’t think it would a stretch to say that many of us have responded in similar manners early in dating. I definitely have and I know plenty of people who have lost the plot over at least one person, especially in the face of losing them. I most certainly cringe at some of the ways I behaved, but I guess we’re all young and dumb at some point. (That’s not to say you are, but I definitely do not think that deep feelings and sometimes cognitive distortion always = bad thing that needs to be fixed.)
