@Uktousa2022 Op, let me tell you about my friend Carolyn.
She moved to the USA to marry her fiancé and start a family together. They'd been together here, for a long time whilst he was stationed here.
Everyone was over the moon for her and was confident she'd be very happy as she's been with him for 3+ years and they were still head over heels for each other.
Fast forward two years and she has a 6 month old baby in the USA with her new husband. Their marriage becomes a war zone and sadly comes to an end. Nothing she did - or him, they just weren't as compatible (after all the excitement of the move & the new baby) as they thought they were and began to get on each other's nerves, despite her also now having employment out there.
Subsequently, they had a fairly messy divorce but manage to be civil enough to co-parent. She has a green card by this point so she's legally entitled to stay in the USA....however....
Her now ex-husband is categorically refusing to allow her to leave the country with their child to do her usual visit to her family in the UK. In fact he won’t even allow her to travel out of their State to visit a friend for a weekend or to take her child on holiday to New York for Christmas!
Turns out this is perfectly acceptable and common in the US (or at least for the state they're in).
So now she's stuck. Quite literally trapped in the USA, unable to even visit the UK without having to leave her child behind, until they turn 21 (I think it's 21, it may be 18).
She's begged, pleaded, even tried coming to a legally binding agreement over it, to prove she'll bring the child back, as she just wants to visit her Mum & Dad as her Dad is very very poorly, but nope! He won’t allow it and if she ignores him and leaves anyway... Yeah, major, major shitstorm will ensue. Kidnapping charges which I believe could somehow be enforced by the US via UK police whilst she's actually in the UK and almost certainly would result in her losing her child altogether. Big trouble.
Carolyn is broken. She's not going to get chance to say goodbye to her Dad in person and her Mum is now too frail to travel long haul too, so she's highly unlikely to ever see her again either.
I'm actually really concerned about her and have been doing all the research I can to try find a way around this but there isn't one that I can tell.
Heed this warning. I realise your brother is out there and that's great but if you have any family here who you love & couldn't bear not to see again, then please realise that this could very well be you!
Even without the family aspect, if you have a child together & then unexpectedly split in the future, unless he signs away the rights to his child (that can be done in the USA, but not here), or he just doesn't care, then you're highly unlikely to be able to choose to come back to live here until your child/children are adult/s.
And please don't say "Oh he would never do that!" Or "He wouldn't ever stop me visiting my family!" as that would be naïve in the extreme! I mean, look at it from the partner's perspective, would you want to give permission to your British ex-spouse and parent of your child to travel over the ocean back to their home country for a 'visit' with your child, knowing that they could easily decide not to come back as you've given permission for them to go? I wouldn't. No matter how much I knew they missed their family! Also never, ever assume you wouldn't/couldn't split up! Even the most connected of couples can drift apart. Even marriages of 50+ years can end.
Speaking of, can you honestly see yourself with this man for the next 50/60 years? If (God forbid, of course) you became physically dependant, either temporarily or permanently, can you see him caring for you? Sponge bathing you, emptying your commode? Sitting by your bedside every chance he gets? The answer should be a resounding yes without hesitation. In sickness & in health, 'til death do us part.
I have vegetables in my freezer that have been there longer than you've known this man. Don't do it. Not yet 🙏 If he's the right man for you, he'll wait as long as it takes....
