Dear Shalini,
It seems like another sad marriage .Just look inside you and be true to yourself.There is no need to feel guilty if you hve not done anything wrong conciously or intentionally.Many atimes,women feel so broken and lost ..there is no other way out but to hve lot of courage,patience and Faith.You have a daughter with you and are not alone.Please ask baba to give you wisdom to take correct action.If he has already filed for a divorce, what reasons is he trying to give?Communication in day life and respecting each others individuality is the key to mking relationships work but both sides have to agree to do that.There are many people sailing in same boat as you.Yes, life is not so simple for anyone,we all meet suffering in some form or the other.Please try to be very very strong .You have to be a good mother.
May Baba Sai bless you.
Babita
