Thank you for your responses everyone. Except for times like the ones I’ve mentioned, he is a very sweet, loving, and considerate man. He is always talking about how he wants us to be closer, to understand me better, and to push to improve ourselves. I haven’t had a partner like him, which makes it feel worthwhile. I’ve felt a huge amount of guilt over being indecisive, which is part of why I’ve had a hard time completely severing ties. The strongly conflicting feelings (love and anxiety) are confusing. The job that I share with this man is not my permanent career. Is there a possibility that his behavior could remedy itself once I’ve moved on to a new work environment where he doesn’t feel so threatened and I’m with him more often? Right now we only see each other once or twice a week, which also rubs him the wrong way. I know that his behavior is unacceptable and that changing things to cater to his insecurities is inadvisable, but I know that this is partly my fault and wonder if he really has just pushed himself beyond his limits in order to continue our relationship and he’s lashing out in ways that he never has before me. His friends and family seem unaware of his bad side and as I’ve mentioned, his ex has come to his defense. I know the behavior says run, but I guess what I really want to know is if there’s any hope for change.
