I met a guy at work during a rocky point of my relationship, who introduced me to his poly-amorous lifestyle. Once we got to know each other, there was some really strong attraction between us, and after some flirting over a few months, we ended up dirty texting each other and slept together twice: once really drunk, and once sober.
After it happened sober, I had an eye opening realization about everything I was fucking up, and how much I love my boyfriend. So I ended everything, and will NEVER cheat again. Honestly made me realize that I want to spend the rest of my life with my boyfriend. What I’m trying to figure out is if I should tell him?
I know 100% certain I will never cheat again, and that he is the person I want forever, so I feel like maybe it would be better for him to just never tell him, and that telling him might make me feel better about my guilt, but just hurt him and ruin us in the process. Just looking for some advice from anyone who has been on either side of this scenario, and how you think the best way to proceed is.

No, don’t tell him. Somethings people are better off not knowing. It sounds like you really do love him so spare him the pain. He will also most likely resent you and the relationship will go downhill. You fucked up, but you’re allowed to do that. People fuck up everyday. As long as you’re not toying with his emotions or stringing him along then I think you are okay in the relationship. Take it as your own secret lesson that taught you what really matters to you!
I agree. I have recently found myself in this same situation. As long as you can heal properly and understand why you got to that place and never go there again….I think it will be fine.
