Most Helpful Guy
Wait what? this whole story that you have told us, just doesn't fit right.
You left, you tried to fix things, he got a new girlfriend, got her a job, is her dad, you went on a date with a guy, and he lost his crap and told you to move on?... Makes no sense to me...
Just don't call him.
What did he miss? Well he's missing out on you, that why you shouldn't care anymore.
