Long Hair or Short Hair?

My hair is around my boobs when straightened, but i have some pretty bad slit ends. I'm not sure if i should just get the trim to get rid of all of them (probably about an inch or two) or just cut it short (a little above my shoulders) because i probably won't get the guts to cut it short for a while again (i had cut it that short about 4 years ago- i had liked it, but i've always liked having long hair)

I don't know if i should just try something new again and cut it off or just cut the inch or two off and let it grow back.

I have a round/oval face with side bangs (i'm not sure what kind of hairstyles best fit my type of face..)

Thanks for your help!!!

Suggestion:

You should at least trim it to get the ends healthy. But you're only 19 and seem to be enjoying your long hair, so why cut it? A lot of women your age chop their hair, but then they are stuck with short hair at least until their early 20s if not forever. And the long hair makes you more unique than all of the other women with generic hair at or just above their shoulders.

There's plenty of time for short hair when you're older.
