would u be angry with your ex for this?

at first I was sad about our breakup, but now I am angry. my ex bf and I broke up 3 days ago and he posted on instagram that he went to a concert to a band that we both like. the only thing is, the tickets came out for this show 2 months ago and he didn't invite me for 2 months. wtf. in those past two months, he got upset that my parents didn't talk to him much during a dinner so he asked for space and didn't even celebrate my birthday with me. then he tries to commit suicide, ask for space, stonewall me, answer me back, tell me to leave him alone, tell me bye, pick up my calls and hang up intentionally right away without saying anything when I am trying to see if hes okay, and repeat. YA IM FKING ANGRY TO SEE THIS POST OF HIM GOING TO THIS CONCERT. WHEN WE WERE TOGETHER HE DIDNT INVITE ME FOR THE DURATION OF 2 MONTHS BUT I BROKE UP WITH HIM ANYWAYS BC OF THE OTHER THINGS HE DID.

would seeing this make you feel angry with your ex?
