Surely it does! Just what I thought, she is more of an adult than him!

Try to be more supportive, or at least understanding of his feelings. Everyone handles pain differently and if this was a serious relationship for him, it may take awhile to get over the loss of it.

I agree with you, #2. Parents aren't as invincible as their children like to think. Just because they're parents doesn't make them immune to pain and it doesn't mean they're able to fix any problem.

Maybe you should give his psycho girlfriend the "man the **** up" talk.

I doubt the Op wants the gf around anymore especially since her dad is going through this little episode.

I think the fact that OP calls the ex "psycho" hints at them not being pleasant

And grown-ups aren't allowed to have feelings?

They are, but if you read it carefully it indicates that the parent is overreacting like a teenager about a relationship. If you think I said that adults aren't allowed to have feelings, in some way, I recommend you read again what I wrote.

Being a parent means putting your child's feelings ahead of your own.

How do you know that the kid isn't the one overreacting.Teenagers are notorious for being melodramatic and insensitive.It is quite possible that OP isn't helping the situation. They would mope if it was one of their trivial relationships wouldn't they?And they would expect their dad to be understanding,therefore they should do the same. Besides,even though he is upset it doesn't mean that he isn't performing his duties as a parent.
