Sticky situation 🤔 should I feel guilty?

So back in January I met a guy online who seemed to be the full package. He made me happy just by his presence everything was great by the end of Feb we had made things official. From that day it just seemed like something was up I felt like a secret. He has a child with an ex partner (who he says is melicious and horrible towards him dating so we have to stay quiet) countless amounts of dodgy behaviour resulted in me contacting his ex to find out where he was one night. Conveniently he was in bed beside her at the time and denyed all of my excistance. The ex is also in a progressed relationship with a new partner... Little too late a few weeks after the seperation I find out that I am pregnant the ex girlfriend was supposedly supportive and wanted to be kept in the loop about my baby as it would be related to her child. So I gave her that privledge. At this moment in my life I feel like I would have loved a child but he relentlessly insisted I had an abortion. Through distress and emotional feelings I forgave him and continued sleeping with him while I was pregnant. It was a false sense of security I completely blocked out that he was a compulsive lier and so was his ex. I have just moved into a new apartment I suffer with Chronic anxiety and depression and just had way to much to think about. The 2 of them where constantly going behind people's backs. When the ex found out that he was still sleeping with me she threw herself on him kissed him and God knows what else. That's when I called it enough was enough I followed through with the abortion as I don't feel being wrapped up with those 2 for the rest of my life would be good for me or a child. I also came clean and told the new partner of the ex girlfriend the goings on behind his back also. The guilt was eating me up that an innocent guy like me was being played around and I knew that information. With my splurging everything out to him one night after a few to many drinks he ended it with the ex and at this point I had stopped seeing my ex! For awhile we seeked advice and guidance in eachother through message, we hung out with mutual friends a few times and only lastnight we drunkenly slept together it was amazing! today has me thinking that i actually really like this guy but should I feel guilty? Should I sweep it under the rug and forget it ever happened.... Is he the honest guy I was looking for all along? HELPPPPP!!!
