Tired of trying.....

Excuse whatever Grammer is fd up today but I don't even care about that right now..... I just need to VENT I just need to know I'm not just complaining.... I hear people tell me try counseling but why when you know the person will put on a good enough act to get you to stay longer then in about 2 weeks you will be right back to trying AGAIN to talk to him about his fd up ways.... I've been married since 2014 we have been together since 2010 when I met him he had his own place he paid his bills he worked he had his own cars he very much took good care of. It's wasn't about material stuff it was then he didn't seem like a lazy person who didn't have his life together now fast forward till now after he lost his job in 2013 and haven't kept one stable job since!! It's either he's not working or he's finding the lowest paying jobs just so in a few weeks he can quit.. our car went down we lost our place I was paying the bills buying the food cooking cleaning doing everything for the kids myself etc anything that needed to be done I paid for.... We have kids we can't keep a place or car bc I simply need help!!!!!!!! And all he keeps saying is he will. I'm so tired of trying to talk to him asking him to help I'm tired of trying to get thru to him it's not right I see married couples living fine and I'm struggling bc he won't help and if he did everything would be so much better everything I'm trying to do I cant.... I feel like if I leave and just focus on doing it completely myself I'll be better off I'm over going thru this he doesn't want to do family stuff everytime we go anywhere he starts a argument it's ridiculous I can't even tell you when the last I've been taken on a date or anywhere I'm really just really tired of EVERYTHING
