Pregnancy drama & lies

So, I’m in quite a pickle! I have been dating this man long distance for about 9 months. I’m 30 and he is 31. We’ve seen each other a few times but hadn’t been able to see each other throughout the pandemic and with our work and school schedules. This relationship was literally the breath of fresh air for me until recently. 2 months ago I saw him and we ended up pushing it a bit too far and had unprotected sex. It was something I was not prepared for but did anyway because the trust was there. Well, that little rendezvous resulted in me being pregnant! When I told him he was not happy and really panicked and I just allowed him time to himself to process the news. He told me with the distance and everything that now wasn’t a good time and then that shifted to him not wanting to ever have children. It was a blow as it was the complete opposite from talks we’ve had before. I would never waste my time dating someone who doesn’t want a family one day and he knows this. I followed back up about a week ago and he basically told me to not expect his presence in the child’s life. That was a blow. I told him I wasn’t trying unravel drama between us and wouldn’t burden him with anything but he still is not letting up. For days I’ve been having this unsettling feeling about him and our entire situation. So, I did some investigating and boy did I find a lot. I found out he actually is in a relationship and may be possibly living with this woman. The relationship seems to date back as far as 2018 and I am completely shook right now. I’m torn on if I should confront him or just let it go as if the only thing I want from him is for him to acknowledge and love the child he made. My actions with him were based on the things we share and connected on but now I feel like everything is a lie and I am bothered by that a lot. It bothers me how someone could lie like how he has been. Why? Why would someone be dating women so far away and telling them that they are single? You know how guys love to say that women try to trap them with babies? Well, actually I feel like I was trapped with a baby! The fact that he gets to abandon ship because he probably doesn’t want his girlfriend to find out just isn’t sitting right with me. I’m usually good at sniffing out a liar but this guy is good. I really don’t even know how to move forward as I never thought that anything like this could happen to me. What would you all do if it were you?
