My bf isn’t ready to be a dad, relationship issues

I’m in a very dark place in my life with little to no support systems so I’m turning here to express what’s currently going on in my life. My boyfriend and I are doing great right now but we’ve had it rocky these past few months and we’re finally back at a good place.

Im currently 6 weeks pregnant. My bf cheated on my earlier this year and I never let it go and idk why but I’ve been wild these past couple of months. I’m now 6 weeks pregnant and I’m pretty sure my bf is the dad. I ovulated June 30th or 31st and my bf and I had sex June 26th obviously unprotected and then on the 28th I had unprotected sex with a one night stand and then on the 30th I had unprotected sex with another guy I met while I was out with my friends but he jacked off and then we had sex and he came but it all came out as soon as I stood up so I know it’s not from him.

I told my bf I’m pregnant and he said he isn’t ready for this but I want my child. And I’m keeping it and I want a family with him so badly. I don’t know what to do or how to make him ready to be a dad but I can’t do this alone. I know he’s saying he’s not ready bc of our relationship issues that he hasn’t let go of, he just makes it seem everything is okay but ik it isn’t. Or maybe it is, since he took me on a date 3 days ago and talked about wanting to get an apartment together. But I feel like I can’t tell him that I cheated because he’s just gonna say it isn’t his and leave and I need him more than anything rn.

Edit - I see a lot of people saying my bf “probably isn’t” the dad but I like to mention the day I ovulated he had sex with me 3 hours after the other guy did and he pulled out but he still has precum & he also didn’t pull out the days before. Not to mention everything came out after the guy from the 30th came in me and I felt it all come out.
