Break Up & Divorce

My Ex-girlfriend wished me a happy birthday. Should I respond?

so, my ex-gf wished me a happy birthday, but I don’t know if I should respond and here’s why. After we broke up and she threw me out of the house we didn’t speak for a month. After we met again after a month she told me that she has been seeing somebody for at least a couple weeks and gave me enough information to see that she was, at least, emotionally cheating on me for about a month prior to the breakup. I also found out that her new guy had spent the night before I even moved out which was 4 days after we broke up. It’s obvious that she was seeing him behind my back from her social network interactions between them before we broke up. She said they have been “friends” on Facebook for a while. So, she cheated on me, left me for him AND, at the time of the breakup, blamed everything on me without any remorse or empathy. I sent her a text saying that I don’t want to be friends and only want a romantic relationship and if she feels the same then we can discuss it. She never replied; she just ghosted me. 3 months later she texts me happy birthday. Should I respond?
