My ex spent the first half of his birthday with me and the second half with apparently his new girlfriend lol

We were together 2 years and have been on and off for the past few months. He brought his birthday in with me, spent the whole morning with me, was intimate with me saying he loved me sooooo much and then through investigation I see another woman posted happy birthday to her love tagging him. I called him and realized my calls weren’t going through so I called off of a text free app about 7 times ( I was emotional) The girl answered saying he was in the store but she was his girlfriend. I definitely told her we had been together that morning and several times this month. I was just talking to his mom. She seems like she’s going to forgive him which is fine because honestly I want no parts. She can have him.

I was having such a hard time fully moving on because I felt like like it was a right person wrong time thing but now I know he’s not a good person at all. No contact should be easy for me. The idea of another relationship ever? Probably not. I’m opting out of dating in 2025 for sure. That kind of betrayal literally changes you as a person. I really did not deserve that. But now I feel okay about us ending.
