Re: I feel so hurt...i dont know if i can cope anymore...
That's really great - I hope everything works out for you.
It's hard not to feel guilty but you have to focus on the fact that you and your husband also need to create and live your own life together.
Get together with your husband and make sure his parents understand that even though you are moving you will still be there for them. If you're not moving far make an effort to keep coming and visiting them and doing little gestures like brining them food you have cooked. It might be hard in the beginning and your MIL might not appreciate anything you do but if she has a good heart i'm sure that will change over time and she will realise that after leaving you had also would have had the choice to minimise your contact with her and the fact you haven't shows you really care.
Pray for the best and inshallah your relationship will improve with them will improve when you leave - I have seen it happen!
