Need a plan of action for saving my family. Wife & I’ve been married for 15 years. We live in FLA?

We were young, i'm 35 she's 37 & have 2 kids, a 13 yr old daughter & 6 yr old son. I work 2 jobs & coach my 2 kid's sports teams. I'm always taking them somewhere when I'm not at work, my weeknights & weekends are very busy. The daughter is in advanced cles and on a travel sports team. Unfortunately, my wife isn't giving us much help. She's always had problems keeping a job. I can't even count how many jobs she's had, I'd say up to 50. She's always worked, just never made more than 13K a yr. I don't make a whole lot myself even with the 2 jobs so we're always just getting by. Up until our son was born, my wife & daughter always had a good relationship. After he was born, it deteriorated. I call it a perfect storm, a mixture of things, that led to this. Wife had always had personality, relationship problems with people before. She’s anti-social. The only people to accept her have been me & her family. I’m aware of post partum, although she has never shown it towards my son. cont...
