Please help me make sense of my deep rooted resentment towards my ds father. I'm feeling it particularly strongly during the holidays. He used to share custody but gave it up a couple of years ago when he met his now wife. He has him a couple of hours a week and allows him to sleep over one night a month but brings him home first thing in the morning. He doesn't have him in the holidays or at Christmas. His family have next to no contact with my child. I fe3l overwhelmingly sad about it and I hold such strong resentment verging on hatred towards my ex. I need to get over it but there's always something there to remind me. Any advice?
