This is really not the time for you to be making major decisions about yours and your children's future. You are understandably feeling rock bottom, and no wonder! You have been through things that no one should have to.
You really should give yourself more time for things to settle down. And stop blaming yourself for the past and your current situation. Your ex is a wrong un, and relationships are complicated things. No one has a crystal ball and we just do what we think is best at the time. It's all anyone does. Your ex has a lot to answer for. It's him you need to aim your anger at.
Honestly your children are better off with you. Do they come to you, smile at you, cuddle you? Of course they do. They need you hun! They don't need anyone else, they don't want anyone else.
No need for a male role model! In any case, this may come into their lives at a later date in the form of a teacher for example. My mum brought me and my brother up as a single parent till I was 10 when she remarried. My brother and I are in stable relationships with families of our own.
You will be stable too, one day soon. You just need some time, and the determination that I know you have. You will get your prize. You have shown such courage and vigour in the toughest of times. I really admire you and when you look back on these days in the future, I guarantee you will too x x.
