As a Muslim husband you have responsibilities, among them (not all) is :

- **Spending**: what you need to provide the wife of food and housing, even if she is rich, Allah says in Al-Baqarah (233) 

> Upon the father is the mothers' provision and their clothing according
> to what is acceptable

- **Habitation**: a wife's right, which is that her husband will create a dwelling on his means and ability, as Allah mentioned in Surat *Al Talaq (6)* 

> Allow them to reside where you reside, according to your means




As stated by previous comment this is more of experience rather than Islamic, the following applies to many cultures

- Women will lose interest in marriage if she looks down at her husband (this applies to her family also), one of the important things that makes a wife respect her husband, is his ability to establish the family home and live independently.

- Some wives (or wife's family) will still look down at the husband if his contribution to the family is less than his wife's.

In all cases, and as you were advised in previous comment you need to try your best to move out with your family.
Move back to the country were you can better perform your duties as husband and father, wife's education or helping her family are not the first priority, focus on having a normal family situation (having your independent home and being in-charge).

I sensed in the question a focus on the consequences and less focus on  the main problem (financial issues), you would not go through most of the issues you have if you are not living with your wife's family, so initially focus on improving your financial position, side by side with moving out even to a simple home.



  
Ask Allah to help you fulfill your duties, hence to fix your situation.
