I would say if you can see yourself working things out with your current partner in the long run, talk to them. Tell them that you aren’t happy in your relationship and you have a coworker who has been making you feel these things. You would rather maintain and fix your current relationship than feed the coworker relationship. See what your partner says and go from there. If you can’t see yourself working things out with your current relationship, it might be kinder to end things with them and move on. Cheating can ruin someone and you’ve already gotten through the emotional side of it. Now you have to decide which person you want for your future and talk to that person and see if they want you as well knowing the full story. Good luck 💛
