New to kegging and my disconnect on the beverage side will not release. Is is normal for it to be so difficult to connect and disconnect to the the ball-lock posts? What can I do to get this free? I’m afraid if I pull any harder, I might break something…
I’ve had stubborn ones from time to time, but the most common cause of a really stuck ball lock QD is putting the beverage QD on the gas post, or vice versa. The gas post will usually be a straight six sided hex with a notch/line in the middle of one hex, or it will be 12-point star shaped and the beverage side will be straight six-sided. Just make sure the moveable locking collar on the outside of the QD is pulled up and wiggle and rock until it comes off. It’s a pain but it will work loose.
I agree with the above advice. You might just have to get a little nasty with it. Have you tried cursing? 
Are you using any kind of lube on your posts?
Cursing is most definitely the answer. I hate when I accidently put one on the wrong post. It goes on easy, but so hard to get off.
Some of my stronger beers tend to have sticky DCs. I hold and pull up with one hand and gently pry with a screwdriver in the other, seems to give after just a second.
also make sure you are using CIP Film on the posts

I’ve used the open end of the 7/8" wrench under the qd to pry it up.
This is what I use.
Pull really hard, they normally release. Next time try so keg lube on the posts, that seems to help me.
