Gosh… I feel so sorry for ur friend. Thank God she has someone like u to turn to at least.
Plusha I respect the fact that u have been in a relationship and u dont wanna walk away after 6 yrs but u need to see this from another point of view. At the moment u r the one doing everything to try and pls him and take his abuse etc while he sits back safe in the knowledge that the rishta is being fixed up n soon he will marry u. Whats to say he wont go one step further after marriage and hit u? He’s treating u like this and ur not even engaged or married what will happen when ur fully his? How will he treat u then? U really need to do something to make him realise that his behaviour is out of bounds. A temporary break is a good idea. U need to transfer the pressure onto him. Maybe then he might realise what he will lose if he carries on the same way. If u decide to go on a break then u need to be strong and stick to it. U keep saying that uv been with him for 6 yrs but do u really wanna spend the next 60 years in the same condition (or maybe worse after marriage)
