Would you break up w your boyfriend if you find out he was following his ex still or that he sent her a message after you guys met?

the guy im dating about 9 days in i found out had sent his ex (who cheated on him in the place they had together by the way causing their relationship to end) a reel and even tho we were not official yet then I had gone to the ER with this man and we had spent the 9 days straight hanging out every single day and he made it clear we are exclusive tho at that time and I had actually seen her pop on suggested on instagram and confronted him and he said they are just following each other and that he and her hadn't talked in a long time. later found out that he ended up sending her a reel a few days after he said that, which to me felt dishonest of him and while it wasn't flirty and it was a church reel i found this to be fucked up. ooh and he refused to block her for months even tho she was still sending him reels, he ignored and didn't open but i was still like why tf not just block her lol. then he finally blocked her after i hounded him about it and gave up and said it was 'for his own reasons' and that he did not want to be told what to do. what do we think, is this trash behavior or am i crazy? he was mad at me for bringing up his ex so many times he said but its like bro i dont think its normal to be following each other anymore or sending reels lmao.
