My son's father is a jerk too. We dated for about a month, and he seemed like the perfect guy. He was divorced, owned his own company, had a home of his own. The first time we slept together, the condom broke, but since I was on the pill, we weren't too worried about it, especially as I was told I was infertile. Imagine my surprise when I found out I was pregnant 6 weeks later. He was out of town that weekend, he said, and we were texting when he asked me why I was so "bitchy" and somehow I just knew. Took an at home pregnancy test, and it came up positive. I didn't want to wait to tell him, so I took a picture of the test and sent it to him. I said "I'm pregnant" and waited for him to write me back. His response was "I'm married". Then he told me he was coming over right now. He was never out of town. He wanted me to get an abortion, my ex-husband wanted me to get a abortion (I was still living with him as a roommate, cuz Washington State is freaking expensive), and I seriously considered it. But I felt like he'd gone through a lot to be conceived, and it might be my only chance at a baby. After trying for almost 10 years, I wasn't going to do that just because his father was a lying bastard. It turned out he lied about everything. He was married, didn't have his own company, and rented. We broke up right then, and my ex-husband kicked me out when I was 6 months pregnant so his 19 year old girlfriend could move in. I didn't hear from my son's father for 4 years after that. The state of Arizona went after him for child support, and during the zoom meeting he said "well, if I'm going to pay child support, I want to be in his life". I agreed to that, we exchanged numbers, and started talking again. We started talking regularly, his wife had dumped him, and he started playing with my head. He started telling me he never stopped loving me, that we needed to be a family for "our son", that he would love to be together as a family. It's like he knew what I wanted more than anything for my son was him to have a father. He did this for 2 months. Finally he came down to meet my son and spend a weekend together. He would drive me around town, looking at all the houses for sale, talking about where we could buy a house "to live in like a family". He was amazing with my son. Just amazing. Finally, his last day with us, while my son was napping, I gave in and we had sex. During it, he stopped me and asked me if I wanted to make my son a sibling. (He knew I always wanted two kids, and I was 39 years old). I considered it, but told him that I'd prefer to wait until he was living with us again. He said that was smarter. He went home the next morning, he gave me a kiss goodbye and told me he loved me. I hadn't said it back that whole weekend, but after he left I decided if we were going to do this, I'd have to open up to him. I texted him 30 minutes after he left and said "after seeing you with (our son), I think I could easily love you again". He texted me back "yeah, about that, I've been talking to an old friend of mine, and we decided to give it a shot and start dating". I stared at that text for about 10 minutes, before I just texted him back "you fucking son of a bitch!" And he just texted me back a question mark and a bunch of confused faces, like he hadn't just spent 2 months love-bombing me, and slept with me less than 12 hours before. He ended up marrying her. My son is now 9.5 years old, and he's only seen him one more time since then. He paid to fly my son up there when he was almost 8, during Xmas break to spend 5 days, he actually paid to fly us both up there (my son had never flown before, and I wasn't sticking him on a plane to visit sometime he hasn't seen for almost 4 years) and I was supposed to fly home on the red eye that night (I fell asleep at the gate waiting for that flight to board and ended up spending the night wandering around the airport until the 8am first class flight I booked the next morning. First class was the only flight until afternoon, and I'd spent enough time at the airport). He spent most of that time my son was up there paying attention to his stepdaughter, he's a great dad to her, but barely paid any attention to his own son. In the year and a half since then, he's called my son 3x, and has managed to not send Xmas or birthday presents even once. My son, who loved him just because he was his dad for all those years, has decided he doesn't care about him anymore. I kept telling his father that our son was getting older, and would notice the times that he wasn't there, but I could never get him to step up.
