Hey mate,
First off, nobody says you don't belong here. People here spent a lot of time learning the MMM way of life as well as the science of FIRE. People just remind you to do your research before you pull the trigger. So in 20-30 years you won't regret going this route, god forbid, blaming the community because you didn't follow the rules.
With that out of the way: I'm also European. I have been living in Dubai for a decade. I know your problems. Rents are sick high here and both Doha and Dubai are designed to separate you from your hard earned money. That's totally cool for me. It's any country's right to chose what to do. After all, I have the choice to leave!
My number 1 advise is to stay away from any venue-entertainment such as brunches, after work drinks, entertainer voucher books and all that "I live away from home in the desert, I am lonely, I am miserable if I don't spend money and I want to live my life, I deserve this"-crap! Trust me, I have seen so many people earning GOOD money for years living a life of leisure but returning home broke, sick (from all the booze) and even jailed (due to financial delinquencies) simply because they don't have their budget in check!
My number 2 advise on living an expat life in Dubai/Doha/Abu Dhabi/Bahrain etc, make good friends. They don't have to be super close. Spend time with good people who are on the same track with regards to finance. Meaning, do not get involved with those bar stars and brunch people. You will piss away 500-700$ a weekend, fuck up your kidney and lose a lot of time which you could use to improve yourself. Make friends who like to spend time with you, not to show off their new BMW.
Number 3: I get why you have a cleaner. I don't but since labor is cheap, I get it. I have two issues with this though. First and foremost, why do you and your spouse get into fights if you have to clean your apartment? You won't have a cleaner when you go back to Ireland. So why don't you start working on that issue first so you won't run into marital issues down the line. The 2nd issue: Some people stare in disbelieve and with a smirk on their face asking me why on earth I clean my own apartment. Yes I do. I wouldn't have a cleaner back at home so why would I get one here. All it does is hedonic adaptation. I get used to getting my toilette cleaned. Once I go home, it'll be much harder to get back in the normal world routine!
Number 4: When I first learned about MMM, I read every single blog post Pete published. It took me about a week. Some blog posts, I have in my favorite list for the occasional re-read. I had that red-pill moment once reading all of MMM's posts. I don't need any of this crap to be happy! This would have been useful in any country, but it is especially living here in Dubai.
