friend w/ benefits turned awkward/STI

hey y'all. so earlier this year a friend/former co-worker of mine revealed that he has had a crush on me since we started working together (for a year). I had also started to like him, as we had gotten really close over the past few months. we started having sex and 3 weeks later he said we couldn't b/c he was coming back to our job and as coworkers it would be risky for us to be fucking. this made me extremely sad, but he explained that he still liked me he just didn't want to risk our jobs. the sex continued at random moments even though we said we would stop. He started dating other people and I explained that it would be difficult for me to be your friend, have feelings for you, and watch you date other people. to combat his attraction to me, he started being really disrespectful, by snapping at me and pushing me away. I cut him off temporarily for this, but found out 2 weeks later I contracted chlamydia from him. when we started having sex, I asked if he was using protection with other folx (oral protection and condoms) and he said yes. He lied. since then he has apogized for his behavior, his lying, and the STI, but I'm not sure if I should keep him in my life. He is a friend who can I talk to about things that I know other people in my life will not understand (e.g. depression, mental health, etc.), but I'm not sure if this can trump his treatment of me. any advice is appreciated. sorry for the long post. UPDATE: THANK YOU EVERYONE! I realized this is very toxic and I don't need that in my life.
