Does the US not have reciprocal CM arrangements with the UK?
You can't apply because he's there illegally, I presume.
Well I'd gather any information you can get whatsoever and report him to immigration.
What's his home country? He'll be forced back there and then you can get CM if he works.
Maybe he'll try to work illegally, or go elsewhere againu, but I sure as fk wouldn't be making it easy for him.
He hasn't seen your child in person or paid a penny towards them so what difference will it make?! Trying to play nice and facilitating video calls has got you nowhere. He's not paid anything, even when you presumably told him you lost your job.
(And they've just used it as an opportunity to exercise their toxic bond by trying to taunt you).
If you think keeping him sweet/being civil is going to make him be a good father in future . I'd be very skeptical about that, given his/their behaviour to date.
If they have kids, do you think she's going to ever facilitate him seeing your child or 'taking" money from hers to pay for yours?
You shouldn't be having to spend your life savings on your - your plural - child.
Maybe you'll never get any money out of him but I sure as fk wouldn't be letting him waltz off without a challenge to what he's done and continues to do.
He fathered a child, he has a moral and legal duty to - at the very least - financially support them.
If they want to continue their fucked up bonnie & Clyde/Mickey & Mallory routine, that's their perogative. They sound trashy, messy and dysfunctional. I'd be glad you have nothing - except whatever cm you can get out of him - to do with them.
You, on the other hand, can focus on creating a nice life with your child and hopefully meeting a much better person - carefully vetted - in time. And there is no time pressure, unlike for many women, vecayyou already have your child.
