Should my wife put her sisters needs before her husbands

You should have told your wife that it was dangerous to take the child out with  all the symptoms of getting a bad cold or the flu. Is she a stay at home mom? Tell her you have a job to feed and clothe the family so you can't just take off at the drop of a hat.Explain that you know she loves her sister and that it pleases you but she is not a single woman now and that the family comes first, especially the children.

I imagine she does miss what her sister does or has, but it was her choice to get married and have a family and that her sister probably misses that kind of loving family in her life. Have her siste call a day earlier if possible to set up a get together when the children are well and you can babysit for a couple of hours.I hope she would that considerate if she had to find a babysitter. I agree she should of stayed home that day but I also have a feeling that you had started to resent this relationship before then. Both of you are going to have to be more tolerant and understanding of the other's feeling and don't go making mountains out of mole hills.Remember to never say anything you don't mean because it can come back and hit you like a ton of bricks somewhere down the line.Good luck.

Hi,

   I totally agree with what A Brown said.  Please sit down with her and discuss these things that are bothering you.  If you can't do this together, go to a marriage counselor.  If your kids are still young, they need both of you in the home.  It's very tough for kids to grow up in a broken home.  I know that you had enough of this, but take your kids into consideration.

    Keep being tolerant of her for your kids' sake.

Take care.

Lets look at it this way YOU MARRIED YOUR WIFE not her sister the two of you got married you did not say you also took her sister. This is your wife and she should put you first as this may be wrong way of thinking. But she thinks she likes her sisters way of single way of life. To me youe wife should take a look at what you have love trust and she is married to you not her sister and she should understand that. Tell your sisterinlaw in a nice way to stay out of your marriage as to the fact of your child being sick and the weather as it was. She should not relay on your wife or expect this out of her tell your sisterinlaw to get her own life and stay out of  yours. But dont say they they can not see each outher.
