strange life, what should the wife do??

I am in no great situation in my married life, but I wanted your suggestions on a recent incident that came across.

This couple had a love marriage. Parents agreed for their kids happiness, but hated each other. In laws are conservative but mil is extremely possessive (can't beat mine though). ILS moved in with son and wife. Wife and ILS were not happy with each other. It seems ILS wanted wife's parents to be respectful to them etc etc, which her parents weren't. Meaning the girls parents were to be submissive, ask them formally to send son to their house for festival's, treat their daughter the same way, ie sil if comes in to town, she needs to be treated well. This was not happening. The wife had a baby and fights happened between parents due to the below par arrangements, like not giving required sweets etc during the baby naming ceremony. Supposedly its the wife's parents that had to do a good function for all the ILS relatives and it didn't go well. This led to a heated fight among the husband, ILS, and wife's parents. Since then the wife and husband are not talking to each other. They contemplated divorce as each couldn't bear their respective parents sadness. Now they are living with each other, but wife doesn't talk to anyone. She doesn't want to divorce for her baby. But has no feelings left for her H. The Mil is completely OK with this arrangement as their son is on their behalf. In fact, she leaves no stone unturned to taunt dils parents for mistreating them. The lady is gutless and living like a stone.

It seems the husband communicated to her that it is how their life is going to be. Among each other the relation has ended and as parents cannot take any more stress, he wants to dedicate himself to them. Oh, it seems if not for the equations with the parents, they are very happy with each other.

The worst thing in all this is, he never spent anytime mingling with her parents via phone or directly. Also, when this lady was pregnant, he didn't spend a single day with her even after the baby was born, as she was with her parents. This was because it seems to be norm in their family.

My question to you, should the lady be continuing in this relationship? She is educated, used to work, but now is sahm. The couple has forgotten all sorts of emotional, verbal, and physical communication. What is the benefit of such a relation where the H just wants to be there for his parents. And thewife is just taking it as she cannot face more hardships?
