About 9 years ago I split up with partner we have a dd together as he was seeing other women. In the last year he has asked to move in with me as apparently he was staying with friends but had to move on. Last September after he stayed with me for four months I found out that he was actually living with the same woman he was seeing when him and me first got together. She had gone on holiday but was emailing him telling him how much she missed him. For some reason she cant phone him until her dad goes to bed. When he moved in with me he acted like we were back together, but she thought he was sleeping on my sofa. Anyway, xmas day he moved in again apparently just till the end of this month. He again is acting as though we are together but not sleeping in my bed and keeps telling dd how much he loves her (never used to do this before). Now he is getting texts all the time and disappearing. We arent back together according to him but he called me darling once. Does anyone have any idea whats happening. Am I being used?
