Dear Eric: I have been in a wonderful relationship for a year now with a man who treats me like a queen, and we have plans to eventually get married. We happen to have a mutual friend, whom I have actually known for many more years than he has. The mutual friend is known by many as a toxic person who is also an egotistical bully, and I believe he uses his friendship with my boyfriend to elevate his own image and legitimize his toxic actions. I would never give my boyfriend the ultimatum to choose me over his friend, but I have to admit, I feel some resentment every time he spends time with him, which is affecting our relationship. My boyfriend is aware of my feelings regarding our mutual friend, but he continues to meet and hang out with him, as if nothing is wrong.
