He cheated and gave me an STI but I still want to be with him.

Hey ladies, haven’t been on here for a while but I have no other way to express what I’m feeling or anyone to talk to. Long story short me and my bf have been together for 3 months now and two weeks ago I started noticing I had weird discharge and itching so I went to urgent care and got tested. The test results came back in yesterday and I was told I have chlamydia and Gonorrhea. I asked him had he slept with anyone besides me cause everything was fine a month ago and he admitted that he did. Just because i didn’t answer the phone one night... I’m not gonna lie I was hoping that he’d say no cause I had such high hopes for him. But I’m completely heart broken behind this. I’m more upset that he slept with someone than the fact that he gave me something I know that’s bad but it’s how I feel. And even though he hurt me this bad he’s the only person I want to comfort me for some odd reason and I’m so tempted to respond to his repetitive“I’m sorry text” idk what to do I liked him so much and I just can’t believe he’d do such a thing.
