Why would a guy leave his 1st baby momma to go and be with the other lady and get her pregnant and went back to his 1st baby mom? I can't understand?

I've known this guy for years years before he and his 1st BM got 2gether and had a child. We saw each other on a fling back then so before her time. Somehow our paths separated and he found her and I found a boyfriend. Me and my boyfriend broke up at the time and this guy went after me again. Him & her was broken up at that time. So fast forward we started seeing each other for 3 years and I found out about them having a child together and he would say nah they not together and blah blah. I believed him and I fell inlove with him. We never stopped seeing one another. Then he started fully investing in me and bought me gifts and asked me to be his girlfriend as they were broken up at the time. He took me to his mom and she didn't seem very fond of me but she knew we had something on. So fast forward he would take me out on dates buy me gifts and stuff. Yeah we made many memories. Beach days just outgoing and fun. I would meet his friends and so. Fast forward we started getting serious this year. And he straight up told me he wants to make me pregnant and we planned the child. Obviously I told him many times he must first marry me before we have 1 because that's how I wanted things. We had sex and I gave into it as I also really did want a baby. So I'm currently pregnant of this man. They werent together went we made the child. He seemed pretty invested into this and was so excited and there for me tru everything since we found out. He helped me financially tru alles. got me a new bed. we had many more plans man. Went with me to the scan recently and this was just last week. This week on Monday this day I just couldn't get a hold of him and I was getting suspicious and I had her number on my phone so I called her. Guess what I found out she is over at his house cause I heard his voice in the background. I immediately called things off with him cause I knew what this was and all he said to me was :'Let me know when you give birth. I won't let you do it alone' devasted.
