I do not know how i feel about my relationship anymore. We have been together 2 and half years and have a baby. During my pregnancy he cheated on me one night when i wasnt there he met a girl off a dating site and took her back to my house. He also cheated on me early this year with a girl from a dating site whos house he went to. I then found out he had been talking to another girl on there 2 months later. He begged me to stay with him and also manipulated me with his children. My partner has several children to different ex partners and one with me. I do not feel important to him. He makes ‘jokes’ about wanting to have sex with other woman and says men can’t just have one partner. He has also been derogatory towards me in arguements he will call me fat/ ugly. I am constantly upset/ angry/ lonley. I feel confused and i am posting to get clarity... can he change? Am i wasting my time?
