My glider seems to hate me I put him on a pouch and he keeps crabbing every time i go near it, he also bites. Does he hate me? Will this ever change?

Gliders don't really hate people your glider is probably just scared and needs more time to get used to you.

living things smaller then a glider are food.
living things larger then a glider are predators.

If he is new to you, he probably thinks you want to eat him, so...
he is scared all to heck of you.

It is up to you to convince him you are a friend and not a hungry foe.
and sometimes that takes a LONG time.

"I put him on a pouch and he keeps crabbing every time i go near it"

Can you explain what you do exactly? this isn't much to go on.

Are you putting him in the pouch and wearing it? or putting the pouch in the cage? is it every time he's in a pouch? is he less crabby when not in a pouch?

how old is he?

how long have you had him?
