My(27F) boyfriend(27M) lied to me and put me at risk
My boyfriend(27m) and I (27f) broke up for 2 weeks back in December. During that time, he slept with someone who is known to sleep around a lot. When we got back together, he didn't mention the encounter and he didn't get tested either. We slept together for 6 weeks before I saw the messages between them on his phone. I felt sick and asked him if he got tested. He assured me he did. I said "let's go confirm that with the clinic." He then admitted that he didn't actually get tested. I know he slept with the person as a distraction and he was too ashamed to tell me. I know he cares about me and he just didn't want to lose me but .. idk how to deal with the fact that I had to pry all this information out of him. He just kept lying until he couldn't anymore. And having unprotected sex with me, knowing he might be putting me at risk.. Disgusts me. I would like to move on from this somehow but how can I ever feel safe with him again knowing he could do something like that? Thoughts ?
TLDR: Boyfriend slept with someone else while we were apart and didn't get tested before sleeping with me. Is it possible to repair this and if so how?
