Ex moved on 9 days later

Recently just got a text from a girl from my exs past (he stood her up, basically was not into her) he reached out to her over the weekend “hey how you been” she immediately texted me and we quickly agreed he has no respect for himself ULTIMATE GIRLS GIRL!! The minute I saw her texting me I knew he had reached out to her to hu.

Why am I hurt by this???!!

Because when we broke up he kept saying “I want to be alone, I can’t do a commitment anymore”

He had no prior experience to dating making me his first gf but I never would have thought he’d RUN to hu and be so desperate!!

Meanwhile he called me desperate for trying to make it work the last night we saw each other…
