<human>: We have been together for 2 1/2 years. I am a physician and she is a nurse. Started my fellowship in another city and she moved to be with me. Prior to moving in with me I proposed (13K engagement ring). We had an increadible relationship until a few months ago when we started to have less sex -about once a week. She and I agreed it was because of the dog that we got, however she also says that her birth control lowers her libido.

We just went on a couples vacation to Punta Cana and then to New Orleans with friends. The vacation in Punta Cana was great but she was on her period and we only had sex once. In New Orleans she partied with our friends until 5 AM two nights in a row. I had to turn in early because I had to attend a conference in the mornings.

When we got back from New Orleans she became more distant -no sex for 2 weeks at this point. She stopped wedding planning and I picked up the slack. She has been avoiding being home much at all -working extra shifts ect. I called her out last night and asked her why she was acting so strange. She told me that she was freaking out about the wedding and didnt know if she wanted to get married. I am not sure what she said after that because my world fell apart. I left and went to a bar to compose myself. When I got back home I found that she had driven to her mother's with the dog but left the engagement ring.

More details: her parents just got divorced this year. She is from central PA. We are supposed to move together to Virginia after the wedding where I took a position for next year.

She is coming home in a few hours -has to work tomorrow. We live together. I still want to get married. What do I do?
