Guilt? Hush Money? Lottery winnings? Apology gift?

Ok so, the douche bag ( better known as my husband) up and writes me 2 checks today. The first one to buy supplies for the kids for school, which I was surprised by that. By the way, I know the bastard is using the checks as a form of establishing he gives me money, in case we go to court. Considering this cheap SOB hasnt been giving me money over the years. im glad to see some. Still doesnt change the fact thst hes a douche. Cuz I think he knows I am serious about leaving his ass this time. Anyway, when I get back from a nightmarish school shopping excursion. He proceeds to announce he's going to a party with his friend, and he's writing me a check to buy an outfit for the party next month. Hell, I'd rather use the money to buy a new vaccumm and get the carpet cleaned. Either way, why in the hell would I go to a party of his friend that knows our marriage is dysfunctional and falling apart? I mean is he freaking kidding? Wait, then he says he wants to go to dinner tomorrow night. Now I'm confused. Didn't he just call me a financial parasite and a leech last week? Am I not the baine of his existence? So, why the 360? Omg! Did he win the lottery? Are we getting the divorce and this is go away money? I just don't get it. Not only is he shady, I told y'all he's bipolar. I swear there is something wrong with him. He needs Jesus. Crazy ass!!!!
