Q: My girlfriend of 18 months and I have a couple of issues. First, she gets upset when I don't call her enough. Second, I've told her I don't allow anyone to leave their things at my house, yet she keeps trying to do it when she stays over. We work together and share a ride to work every day. We talk off and on most days at work, and we talk going to work and going home. I am not a phone person. I don't call family or friends. She is in her mid-40s and I am 56. She gets me 90 percent of the times she calls me. And she calls me any time of the day and night. We have an exclusive relationship, and I really love her, but in a recent conversation she came just short of calling an end to our relationship. These two issues are the only things that she said she has an issue with. Please help with this. She thinks we need a mediator.
