Feeling stuck

I've been married for 6 years. And have 2 beautiful daughters. We've had our ups and downs just like any couple. 3 years ago we almost went through a divorce but him being forced into marriage counseling by his boss (he was military at the time) and me wanting to work on everything to save my marriage and family we worked through some unresolved issues. Then he went to Korea for a year, and when he returned seemed like everything was great and we were really communicating and working through everything just fine. But we are down that road again. And this isn't only the second time we've been here. This is like the 6th time in our 6 years of marriage we've been down this path with threat of separation and divorce.

I'm doing everything. I'm the one working now and providing for my family. I'm the one having to do things with the kids and clean house. All while dealing with bipolar disorder and anxiety.

He just started going back to school, but he doesn't work, which doesn't really bothered me if he helped out around the house. He doesn't do anything around the house until I finally get so angry with him and nag him enough to where I can finally get him to do some dishes or fold laundry. And he doesn't do anything with the kids either unless I make him. All he does is play video games all day, and wants nothing to do with me. And if things go wrong it's automatically my fault. I just feel stuck and don't know what move to make next
