Too bad, when you start thinking with your penis, shit like this is bound to happen. too little too late. so here is my two cents, like a khaki wearing scout be prepared. Either way one or both of em will know eventually if you already haven't told them.

Scenario 1:
Your wife will and should leave you once you tell her and assuming she will be pissed and file for divorce, she will more than likely claim for your property and rightfully so she should. Nepalese law favors women in this situation so at the end of the day you will end up losing most of what you own, well maybe not everything you will still have my two cents.

Scenario 2:
You leave/abandon your Israeali gf and your to be child. In time she will find you and claim for child support if not for your property. I am no lawyer or SME and don't know the nuts and bolts regarding how this scenario might play out but  most of what you own might end up going to the lady and the child.  I have heard that Israelis women/men are well trained in combat situation, to make matter worse you might also get your ass kicked. Please take some TIE CONDO lesson for self defense.

What you reap is what you sow.
