How do I love me ?

I said I'm done with my boyfriend of 6yrs. We have three beautiful boys together. The relationship was very distructive on my part . I went through everything possible. Now I want better no more one one more chances. Or telling me what I'm not enough of. I wanna love myself & put myself first boys included. I want to beat this & never turn back or walk into some one else like this. How do I do this ?
