My fiancé got married to another woman

He and I was together for 3 years and engaged for 1 year. We got engaged and then had a baby. He wanted a child real badly and kept forcing into marriage. My fiance went and got married to another woman behind my back and I found out 5 months into their marriage when she called while we were home. We have a daughter together. His family and everyone around us knew he got married except me. His new wife is the so called friend he told me that I should never worry about because they were friends for years and she knew he and I were engaged, had a date for our wedding, a child together and we lived together. Now I’m trying to move on and coparent as much as I can, each time he calls , he always tries to bring his wife up in every conversation. It’s like he’s rubbing it in my face. He called tonight and randomly brought her up 2 mins into the conversation saying that our daughter is really friendly with her and she would never hurt her. I’ve never once stopped my daughter from being around her or turned her against his wife. I don’t want to hate her, but I do. I hate them. They ruined my life. It’s been almost a year and I’m still trying to move on. Now I feel like I won’t love and trust another man. I still love him. I did everything for him and he betrayed me. He didn’t even have the heart to tell me that he got married much less to apologize. How can a person be so heartless
