We got blindsided by your friends
All in a hurry like you had to go
Didn't they know you can't leave someone

Why doesn't he get that she wasn't into him? O_o
On the assumption that you're right (not disagreeing), he should learn that his entitlement is not really something morally justifiable.

Maybe the song's a commentary on rape culture and victim-blaming.
Don't quit your day job? :-)
