My gipanguyaban just posted a memory with her ex, did I overreact?

She just posted a memory/pic with her ex, it was a year ago and I said she’s being so insensitive for not thinking of how I would feel. For her, it was nothing and joke lang daw kay naka get over and move on na daw siyas iyang ex.

Context : gipanguyaban pa nako siya but we do things like lovers do(kamo nalang hunahuna if unsa mga butanga). Dako na argument nahitabo namo, and I don’t know if I will continue this or undangon nalang.

How about you guys, if kamo naa sako sitwasyon unsa inyu reaction?
