Calm down! Breathe! It's not over until the fat lady sings or you decide it's over.
Yep, he's gas lighting you and looking for any and every reason to leave, i.e., bringing up your faults, etc. Please do not buy into that mumbo jumbo.
When you go home, act normal. I know it's going to be difficult, but the more normal you are the better. Anger isn't going to get you anywhere w/him because you've seen that he turns the tables back on to you. They won't admit that they are wrong because to do so who shatter their fragile selves, their moral compasses.
You'll know what to do when the time comes. If he's telling you about getting things done, checking the bills and trying to get bills paid off or lowered, then he's been thinking about leaving for some time. If he goes, wish him well and be sure you've got yourself covered in the financial department.
Breathe! You are going to be okay.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
