Always something happen

I decided to back to Japan in April 2011.
I am looking forward it but today I got a message from my youngest and she says that her husband has been upset about my eldest, her husband and me.
He was thinking we, three people made a fool of him, and if we would not apologies him, he does not want to see us any more, moreover he does not want to me to see my grandson.

Since my youngest got pregnant, I was always their friend side. He might misunderstand me, I hope.
However during they built their new family, I was not there (I had been away to NZ) so, instead of me, his mother looked after them. He might be upsetting about it.
I do not care about that I can not see my grandson, because he, my grandson, does not know even me. But I feel sorry about my youngest a lot.
It will take long long time for he to understand me, or he will never understand me.
Because his mother loves him a lot, then gives many things to him, but I don't.
Should I look after my son in law as well as my daughters?
Yes, maybe my unwelcome attitude made them unhappy. I am a really awkward mum and mother in law,too.

When I am thinking about, I have never invite them to a meal. It is really bad.
But when I was in Japan, I did not have such a habit. 
We were looked like a crazy family, the house is always dirty, I was not at home in the night often, and still I can not afford to do anything for them.
But that is ME.
I was and am busy enough to keep the relationship with my real daughters.

Also when I am thinking about my mother, my previous husbands were not very happy to stay around her. Yes! guys need guys. I did not have husband.
But it should not be an excuse... The problem was ME.

I will just pray. Everything will be get well by next spring, I wish!
