dealing with loss of spouse due to maligant melanoma with problems from relatives help

One sister wanted to take him out of hospital to a small town to pray for him.  Before he was diagnosed she tried to connect him with another woman who was also a religious fanatic, I got into an argument over the phone from the hospital and was very upset as I felt like she was trying to get him to leave me.  We had been married over 25 years, not all of them happy as I was often told lies.  I still loved him and never would abandon him, but his family seemed never to like any of the inlaws if they were not pentacostal.  I am having a hard time with this as in my early childhood I was abused by a step-father.  This caused me low self esteem.  I wanted to think my husband really loved me as most abused children are looking for someone to love them as they should be loved.  I am so depressed over this all and don't know how to change how I think.  Please help.
