I 've been married for just 3 years and my wife is 24 years old. Our marriage is struggling and we have started to sleep in separate rooms but still make love occasionally. Recently, I noticed that my wife has bought sexy underwear in fact the kind a woman would wear on her honeymoon. But she does not wear them for me only when she is going to work. As if that is not enough, 2 nights ago when I took my shirt off, my wife asked me why I shaved my shoulder hair. Now what is strange is that I have never had hair on my shoulders. I told my sister about this comment and her change in underwear, because we are very close and she told me she thinks my wife is having affair with a man that has shoulder hair and so just mistook the 2 of us. I have now lost trust in her. Is my sister right? Can I trust her?
