Husbands anger issues

So my husband can’t seem to let go of things and escalates them and instigates people on Facebook about different family issues. I’ve noticed over the years he’s got anger issues and I’m so tired of fighting with him to try to get him to grow up. HELP! What do I do?! No matter how serious I get about divorce he doesn’t change and honestly I can’t support myself and children alone, we don’t have anyone to lean on in that way either. I make decent money but not enough for living, food, and daycare expenses. I’m so lost. I love him so much and wish he was like he used to be but I’m seeing less and less of that person everyday and feel like I do not like who I am with him either. I’m terrified it’s never going to change or get better. Please pray for me and my children, we could use all the help we can get in this matter.
