Is it worth staying just for the kids

Is it worth it honestly 😞 I try and try but every day all I can think about is everything he has done to me over the years. I just I don't want to break up the family but it's starting to just feel normal when he does something out of line like cheating once a year on me emotionally/physically. Never once have I stepped out of line but it's always at least once a year for him to 😞. It's been 8 years! 8 years I put up with it and every day my heart hurts more and more. Every time he says I love you every time he says I am beautiful and he only has eyes for me. It makes me sick now 😞 he told me he would take the kids if I left I have them 24/7 he doesn't even wanna help with them he has worked maybe 2 out of the 8 years and thats if you add all his jobs together 😞. He told me he would tell them it was my fault we split and how mommy is breaking up the family 😞. And let me add the first time I was 6 months pregnant with our dieing son 😞 he even used my old phone as I slept on his chest 😞 to tell a girl he loves her and would get rid of it all by morning I don't even trust when he stays up late playing games now because of it 😞

Is it worth it in the end honestly......
