Thoughts?

So a few days ago my boyfriend basically friend zoned me and this was because I expressed how hurt I felt in the relationship. He didn’t show up for me on my birthday, Valentine’s Day and more and it all took a toll on me. He basically said that he can’t make me happy being in a relationship etc and said we should just stay friends. He’s obviously not my friend but I agree to stay cordial. He would still communicate with me after the breakup through text and sometimes he would also flirt with me…. Out of nowhere this morning he asked me if I was back on dating apps? This wasn’t the first time he mention something like this to me. I told him that him asking me that question made me feel like I’m someone that moved around fast. It hasn’t been a week yet since the breakup. He said my response bothered him and I could’ve answered his question differently. Like he just started blaming me for how I answered and his question was very rude in the first place.
