Leaving husband

Hi ladies. Has anyone felt terrible about leaving there husband I’m thinking about it but what’s holiding me back is he doesn’t have anyone but I know I’m treated bad. He doesn’t watch the kids and when he does he stays on his game when I’m sick he won’t go get me medicine or anything when my boys r sick he won’t take them so I can work or to the dr. He use to threaten me he would leave and now I’m just not happy I’m sad all day or angry and I’m just a emotional reck.
