What are some good movies to watch after a breakup?
Like are there any movies where the guy breaks the girl's heart, but then she get's a happy ending and he doesn't? Or where the girl finds true love after having her heart broken? Just something that will make me feel better about my situation.

If you want to feel better then you stop dwelling over it... and watching a movie is dwelling over it.

Anything less than putting it behind you... not allowing yourself to spend time thinking about it... means you are dwelling over it... and you can't move forward until you stop trying to live in the past.

Consider it like pulling off a bandage that's over some body hair... you can do it quick... and yeah it hurts but only for a little bit... or you can pull it off slow relishing the pain as you feel when every individual hair gets pulled out.

Terminator

Road Warrior

Equilibrium

Sin City

Exorcist

Just to name a few...

But yeah, smoothy is correct. You stop dwelling on it. You get out and do things with friends and family.

These cover all states but you might find them enjoyable. They might bring on the tears, which will help because they are cathartic. I guess the other two posters don't understand about catharsis and getting it out of your system:
Cabaret (1972)

Untamed Heart (1993)

The Truth About Cats & Dogs (1996)

Sweet November (1968) ~ this is so much better than the remake!

These aren't necessarily girl gets different guy at end after heartbreak.

Also, books to read --

Strunk & White - The Elements of Style
