Is the wife wrong in this situation?

Read the description before you respond to the question. I'm watching a reality TV show and this woman found out that her husband has been cheating on her with her best friend/assistant. Later, she found out that he might have have a 2 year old and a baby on the way. The husband's 21 year old son just got shot to death and the wife came to the funeral and paid for the funeral reception (in the midst separation, but before divorce). Now, the husband is upset because he feels like the wife hasn't been there to support him like she should because she distanced herself after the funeral. So, my question is do you think the wife is in the wrong or do you think she did enough due to the circumstances?
