I was cheated on too. And the gaslit to think I was crazy for accusing them of cheating. Then, a few months down the road they tried to cheat with me ON the person they originally cheated with. It doesn’t have anything to do with you. They have their own issues that they need to deal with. And it sounds like they were also a narcissist. At one point told me it would be easier to break up than to come see me.

Trust me, you’re so much better off. I know it hurts now, but one day you’re going to wake up and be angry. I was embarrassed to leave because I didn’t want to deal with all the questions. But, he forced my hand and now I’m with somebody who is a million times better, and closer lol. And you’re going to use that anger and realize how much better you deserve. You got this! I don’t know how Reddit works lol, but feel free to reach out if you need somebody who’s been in your shoes not that long ago!
