<human>: Can you condense the text into three sentences or less?

Hi guys, first off thanks for any help you can provide me. I'm really looking for information from both sides as the divorcer and divorcee. 

Background: we've been together for about 3 years. We're both in our early 20s and I'm a female he's a male. We will call him Jay. 

Recently things just haven't been the same. And I'm not sure how long you have to be unhappy and try to make things work before you give up. I'm honestly ready to move on and I've brought up divorce a few times and jay just brushes me off as if I'm lying or trying to get attention or will bawl his eyes out and says I can try but he won't let me. I don't like hurting people so what is the best way to let him down? Jay seems to think I'm his soul mate, but we honestly don't want any of the same things in life, one of them being children, I don't want any and he wants 4 kids. 

Side note: he has a short temper. I might even say he's bipolar with the way his mood fluctuates. That being said, I feel like if he got mad enough he might hit me. So that's another reason I'm turning to you in private reddit.
<bot>: I want to divorce my husband. What's the best way to let him know and him believe it's what I want.
