My ex and I broke up back in the middle of October because I found out she had been cheating on me for several months. I was obviously devastated, and the relationship was to the point where I had bought an engagement ring, asked her closest family members for permission, and was just waiting for the right time to propose. She knew I had the engagement ring, and we talked about wedding plans, and when to do the proposal very openly with each other. I had no idea this was going on.

Now, I let her keep the apartment and moved back in with parents, and am having the normal post breakup feelings. The part that is killing me tonight though, is throughout this whole process she has not admitted to seeing this guy. Without going into detail, there is no doubt they were together. Short from catching them in bed together, there was pretty much every other type of evidence. Tonight, I had to look at her Instagram and her bio says they’ve been together since August.

I feel freshly betrayed and livid again because she won’t admit to my face she was cheating, but is flaunting that they’ve been together now since before we broke up. I don’t know how to handle my emotions and move on. I also can’t stop checking up on her social media. It’s like an addiction and I don’t know how to quit it.
