I posted the following on your other thread about whether your fiance's behaviour is abnormal but as I meant to post it here I'm duplicating it herewith:
On reading your 2 threads on this board, it would appear that you and your fiance are fundamentally incompatible and there will need to be a lot of give and take on both sides if you're to build a bridge that will span the cultural divide that exists between you.
Your Chinese heritage has made you far more driven to achieve material wealth and success at an early age than your Ukranian fiance and you resent him sending money to his family members while they are not, to your mind, in 'need' through ill-health or old age or some other affliction.
In this, it would seem that you are not aware of the poverty and lack of opportunity which exists in countries that were formerly members of the USSR, or of the fact that Ukraine is in crisis due to the slow speed of reform and continued decline in living standards and the annexation of Crimea by the Russian Federation.
It's laudable that you're holding down 2 jobs in your desire to 'get ahead' by getting your mortgage paid off quickly but it's not only unreasonable of you to expect your fiance to follow suit, it also puts the quality of your already somewhat fraught relationship into question if you both work so many hours that you have little time for each other.
Your ambition is such that it's probable you will look to buy further properties when you've paid for your current home and this gives rise to an endless treadmill with little opportunity to stand still and savour each and every achievement instead of rushing to the next self-imposed challenge.
Imo gifting your fiance with an equal share in a property to which he has contributed considerably less than you and your dps was a grave error of judgrement and you're best advised to endeavour to buy him out for a sum that is not much more than what he's actually put in to date and either look to sell or take in a lodger, or lodgers, to make up the shortfall in the mortgage that will be caused by his absence.
My limited experience of Russian men has left me with the impression that inside their severely pragmatic exterior lies the tortured soul of a romantic poet and these divergent aspects of the Slavic personality occasionally reach an accomodation with each other by means of lots of navel gazing philosophising accompanied by copious amounts of vodka and some exuberant dancing. I love 'em... but I wouldn't want to live with one
