You say you knew he was a flake from the beginning – yet you dated him, wanted to keep dating him, texted him asking if you two were still on, and now you’re pissed off because he cancelled a date - ??
By the way – this isn’t necessarily about online dating or match.com.
I am a bit confused....are you angry about him needing to cancel the date due to work or did you just not like him???? In your post you call him a flake but that might not be the case...at the same time you list some negatives about him that seemed to not be something that you liked about him. I know you were venting and I understand that but I think it's important you determine exactly what it is with this man that bugs you so you can file him away in the right category.
Lives are busy and sometimes dates are canceled but try not to take it personally.
