Input: Hello there. So this happened years ago but I want to get this lingering question answered once and for all.

So my ex(we were exs at the time of thr event) and I were hooking up after some time being apart. Nothing too serious just a fun time, and definitely not exclusive. Also we were wearing condoms. This was around Christmas. On new years I went to a party in seattle and had a crazy night that ended in me having sex with someone I met that night. I knew that telling my ex about it would cause a lot of emotional turmoil, and i was hopping on a plane to guatamala a week later. So i didnt tell her, and we continue to have sex for a week. 

Not that this changes things but the next year around christmas we hook up again. AFTER we have sex she tells me she is dating a man 40 years older than her and is using him for money. I will say that i felt super weird about that because i felt like even though we wefe broken up and nom exclusive, her dating someone else was information i should have before deciding to hook up. 


AITA?

not telling my ex that I was hooking up with again that I slept with someone else
