Men don suffer oo.Someone that brought you and your kids to the Uk has now become "useless"simply because you are now entitled to the Uk benefits.

So what exactly do you want from US? Continue testing the waters until you find Mr Right while you're still married to your estranged husband
. As you've listened to your pastor's prophecy, when both your sin and that of your husband's are compared by a credible court of public opinion he will be a remarkable saint.

Madam, I'm not judging you o, but do you honestly think in your heart of hearts that you have been fair on your husband. He may not be here to defend himself, but there is a judge above all judges that will give each person according to their deeds. Simply because you are now claiming benefit from the government he has suddenly become useless. Will you say the same thing if there is no benefit system? This is happening a lot among nigerians in the western world, especially when the women have been brought by the man from home.
Search your conscience, if you think you have done the right thing, then good luck otherwise ask for God's forgiveness and retrace your steps. My 2 cents.

@mutter, when he was with us, he worked full time and paid his own part of the bills like rent, council tax and all that, however apart from that, nothing else for me and the kids. he would have abandoned us without looking back if i had not contacted CSA to track him down and make him pay child maintenance, that's how bad he can be.
@edwife, My current partner is divorced, so he was like my comforter while I was going through all these, and as a woman, these things affected me a lot, else I would have suffered depression from deep thinking. I was weak and vulnerable. While not justifying seeing another man while married, i had no choice at the time. But a man who leaves his own woman to chase other women has created the opportunity for other men to chase his own.
Like I mentioned, my pastor is an elderly man that knows most of my travails. He had intervened on many occasions but things did not improve. My current partner is kind and caring.

for the bold part.

Your current partner is kind and caring yet he divorced someone or someone found a reason to divorce him. If i were to guess his story, it will be the wife was "useless" and busy chasing other men around.

I don't have any advice for you. Make your bed and lie on it.
