Considering Moving Abroad with Boyfriend to Manage Medical Issues

I need advice. Ok so in my last post I was looking for a roommate and we might have a solution but I'm wanting to see if my other decision is smart too. Let me fill you in. Due to my medical issues, I didn't feel comfortable having anyone other than my boyfriend or roommate currently, living with me. So we're trying to get my boyfriend here before the lease is up in may. We have the ability to do so if we collect the amount of money needed. He's from the UK. So what I'm going to suggest is this but I'm not sure it's a good idea so I wanted another opinion. Maybe we could alternate every few years or something I don't know I'd probably be happier in the UK anyway LOL. Because I get an apartment out in South End and you and I could live together while he could still help his mom that way he's not gone forever and it's probably going to be easier for his mom to understand why he's leaving and his friends, his sister, that way it's more of a trip for a few years than it is a move. That way he can help me until we save enough money then go somewhere where I'll statistically be happier. Global Healthcare earlier this year, showed that 67% of people who'd moved abroad found that the experience had affected them positively. We'll save month and have at bare minimum $18,787.28-20,000 or £15152.97-16131.10. I have some apartments I like. The average moving overseas cost is $5-8,000 that they recommend in statistics to have at least before moving. so that with that apartment times six so we'll have first, last and deposit plus money saved in case there's trouble with rent or something. Doubled for any moving hexpenses that might occur. Does that sound smart? 🤓 £134,466.43 or $1,666 2⁄3 is all I'd need to save each month which sounds like a lot but that's £33590.18 or $416 2⁄3. Between the two of us? that's doable. And these are numbers for doing it within a year to make that kinda money. I've already done the math. I think it's right. We'd save money on shipping stuff over here because we'd be going back and his family lives there. 🤑 💰 We'd create a plan to slowly swap over my medical stuff and find good doctors over there. Get me a visa, new passport, and change my name with all legal documents so I'd have my chosen name on everything. We'd find an apartment and discover costs for moving me over, utilities and others costs I might have. In addition, I'd be saving for healthcare since USA and UK healthcare isn't compatible. In addition we'd have tested how well we work living together before trying it in another country. We'd both probably get dual citizenship and get any medications needed transfered. I'd give us time to slowly ship my stuff over instead of all at once. What do you think? What else aren't we thinking of as well?
