Re: Who is to blame ?
Based on the just **the information you have provided us with, **it is the son's fault.
Whatever issues the son might have with his own mother and siblings.......he has an obligation to them. He has an obligation to the woman who took pains to raise him without a father.
The daughter-in-law might not like her in-laws, but that's her problem. The son shouldn't be treating his own family as though they are in-laws.
But there are usually two sides to a story. And we don't live with the son or his family. We don't know what kind of upbringing this guy had without a father. I have seen and heard of sons who grew up without a father and faced a harsh upbringing full of emotional and psychological pressures from their mothers. Because of this, the family unit as a whole (not just the son) becomes dysfunctional and the son decides to distance himself from the family.
^ I'm not saying that that's the case with the guy in your post. But i'm just sharing an example of a couple of situations that I've seen and heard of.
Out of the two individuals, the son is at fault based on the information you've given. However it would be interesting to know why the son is treating his mom and siblings like this. What is causing him to abandon his mom and the people he grew up with? It's not easy to abandon your family like that. The bonds of kinship are usually so strong....that it's painful to make the decision to sever those ties. So, something must have happened that has caused the son to behave like this. Something that goes beyond the desi explanation that maybe the daughter-in-law did black magic on him to separate him from his family, LOL.
