Just have to comment this -
OP seems to be angry, because of the negative answers.
Of course would everybody happy for positive answers, but shall people with a lot of experience and living time in DR Lie to you. ?
You say you are going to do it anyway, so why care about negative answers. It is your life and your decision .
But my advice is to think twice about this.
If you ask people, what kind of business they would start , will many say a bar, restaurant or nightclub.
Who didn't want to mix work and pleasure, like be a important and popular club owner.
The truth is , there is also a lot of paper work, lonely hours in a office.
And many working hours every day.
The owner of one of the most popular restaurant on the beach in Sosua, work around 12 to 15 hours a day, 6 times in a week. Up early in the morning to buy food. And for two years ago,burn this place down, only good friends help him to come back again.
And in rain periods, can the beach have very few costumers , I know one girl that work in the beach, had try to prostitute herself to get money to survive.
There is nothing as Faithful costumers, they can very fast change their favourite place , so for been the most popular place to no costumers can happen fast .
Let say it comes a new restaurant close to Rocky, same prices and quality and they offer the expat and regular costumers 20% of normal prices, maybe then will Rocky loose costumers .
Or Bermuda bar, loose German tourist or they find out their beer is 40 peso cheaper at The neighbour Flow bar.
There are many places in Sosua, that was very popular before and now has very few costumbers.
And some just start a bar/nightclub without be to smart, like the new nightclub close to the four roses and hotel Europa, was very few costumers there after opening.
And there is a lot of bars/nightclub is Sosua, that change owner after a few years
I would personally start a place where it would be locals too, like in Santo Domingo or a big city.
Real estate is going down and 10 % lesser tourist last year,
And what about Cuba, a lot of invest there from foreign hotels, for it is only a few years before the blockade will be over and Americans can visit legal.
And who will invest you or your boyfriend, who has the money to invest or who will loose money if it become a failure ??
I had a Cuban friend before,that all the time wanted me to invest in project or open store /bar, And he believe his ideas was so very good. I didst agree and it was my money and I that would have lost them. It is so easy for other without money to have good suggestions and plans, special when they have nothing to loose , only to gain since it is not their money or future on risk.
But anyway, just do it, follow your dreams, but accept it can be a lot of boring and hard work and maybe not so profit as you hope, and even a failure, but then without money will you at least have the love for each other. Except that hard work and bad economy often destroy relationships.
