From what you have described you appear to be in a terrible situation but can I point out a couple of things from an alternative perspective?
Although unusual, there is nothing wrong with this in my opinion as that is what one loves when one loves another as you clearly stated that you did. You are clearly in a better financial position than him so fair enough.
Many on the forum have spent vast sums pursuing the one they love! That shows they love their partner and the money they spend is an investment in their future as a family and is thus, for them both!
The fact that you connect these two sentences together in a paragraph suggests that you believe they are somehow connected but have not really explained your thinking.
You go on to explain that you are a workaholic; that causes many problems in relationships. Although not my pastime, perhaps your husband goes out as he feels neglected. You said that he received some money from his employer; presumably that was a one-off payment as he is clearly not undertaking work for that employer whilst in da Phils.
It seems that you are saying he spent some of the only funds he got from his employer whilst there taking you out but now that he does not have anymore he cannot do that. You want him at home but what is he to do whilst you are being a 'workaholic'?
Amiga, why did 'you' decideto buy a house. Marriage is a joint commitment; it seems as though you are both operating as single people.
Surely, if your husband wants a multi-cab he is trying to work to generate income. Also, is it legat for a Brit to drive a multi-cab? I've no idea although I can foresee a few problems.
It seems that you are both at fault here and do not communicate enough as you are not a team. Noone should put their hands on anyone be it a man hitting a woman or vice versa.
So you should let him sleep in 'your' room and I imagine that you tell him not to disturb you when you are being a 'workaholic'.
This does sound bad of him but in a marriage you cannot keep tallies of what who does what and how much it cost.
You cannot have it all your way. It seems that you believe everything you do is correct and everytjing he does in incorrect.
Remember, almost all men will feel awkward when not having money and living in their inlaws house, in another country and with their wife indicating that she is doing everything and he is not doing anything meaningful.
You both do things the other does not like and need to learn to compromise.
My view is that you saw something in him to make you want him there with you. He presumably felt the same.
Now that you have hit obstacles where you cannot both be as selfish as you want, you want out. Well, that's up to you but I would encourage you both to grow up and think of how you can both be better spouses for each other and work at your marriage.
All the best!
