Cheating

So I got cheated on by my boyfriend of almost 3 years. We also have a 6 month old son. He’s talked to girls before but this is his actual first time having intercourse with someone. I noticed that he was being weird and distant so I literally begged him to talk to me and fix things and he just wouldn’t. Which was unlike him. So I asked him if he had sex with someone (hence his guilty actions) and he full out said yes right away. So I asked why and he told me I stopped making him feel good and I’m not supportive. (Which is true but in my defence he kept talking to girls and not doing the changes I have asked of him so I didn’t feel the need to do his either) and I asked him the story and he told me that “he couldn’t get hard so he only went in one stroke with a condom” so I said okay I want you to get checked and he said he already did. Which that was fishy cause if you used a condom I don’t think you’d rush to get check (I found out the day he got the call back, so approximately a week later) so I pushed for more. And he said they had sex with a condom and he bussed on her vagina and then went back in. So he bought her a plan b. I ended up having a mutual friend with the girl so we talked. And his last story matched her story. But guy I need help. I’m so in love with this man. We just started a family, and live together. He’s been extremely apologetic. Crying a whole lot. But tears mean shit to me. But I can see hes  generally sorry but he Still cheated and my hearts still broken. What dooooo I doooooo
