I am in love with my wife's sister.

just like what you just said, "how could you do that?" how could you do that to your wife!

oh God your just getting yourself in complication. You know its just a state of mind. if you tolerate it surely that will you feel but if you think about your vows on your wife and your responsibility and love for her im sure you will be faithful. The devil is just around you and trying to tempt you so dont be fooled.

If you want to ruin your life go for it but don't take your wife's family with you!! Don't do it, you will never be able to change it once you do it !!

Are you sure about that? Does your wife's sister know about it?? I suggest that you should wait and think carefully for a while before making a decision because this is very serious, and it can hurt both your wife and her sister. Also, perhaps it is just that you don't know what you are thinking, so be calm down....

forget yours wife sister and carry on your married life with your wife,,,,,,,marriage is a bond of trust there is no chance for cheating in it,,,,if you do that there will be no one to take care of you ,,,,,,

Oh, thats a disaster, better avoid her if you dont want trouble.

When she is nice than for what u r leaving her... moreover she will be hurt of this non sense act of yours.... Left that stupid relation n have some morale values too,....

I don't know as I have never been like that myself. It sounds like you have some serious thinking to do. Since you say you are thinking of leaving your wife you have some expectation of having a relationship with her sister?

aw geez...!! Pal, you only creating problem. What's in your mind when you marrying your wife anyway?!?
