Reposting: AIO for wanting to end my 9yr relationship over this?

My “partner” and I took a family vacation at the end of April.During the 5 days that we were there, my partner met a stripper at a club and started to “fall” for her. I found the following messages from their first days of communicating. He fought her $475 worth of Gucci & YSL perfumes and has sent her almost $8500 in the 3 weeks we have been home. We’ve been together for 9yrs and have one child together.

No, this is not bait. I’m hurt, blindsided and in just such shock that I would like to be reminded that this is an ok time to be done and leave with my kiddo.

Updated for her privacy too.
