So a lot happened last night and this morning. He got here at a fairly decent time last night and we sat down and talked. I was weak and begged him to stay which didn't work. So I put up my wall and started to shield myself from the pain. We started talking about stuff and he informed me that him and his "friend" who is a girl were telling each other that they loved each other and after he moved out he wanted to start a relationship with her. So I told him that my 2yr old would not be coming to visit because I don't want her around this girl. She doesn't understand yet. I told him that coparenting with his job and schedule would be difficult because he works most weekends. So when I started to talk about putting up my shield and how I needed to be strong for the girls he told me to come sit by him. I did. He told me to not put up my shield and that he was torn. He wants his family but he also has feelings for her. I told him he can't have both. He had to choose . He chose us. He texted her and told her that he was going to try to make it work with me. We had sex twice last night and this morning. We get up today and he seems to be trying a little but he acts like someone died. Did I do the right thing by taking him back or should I just try and go out on my own?? He has been my rock, my shelter, and is the father of my children. We have been together for over 14yrs. I don't want to just throw all that away.
