Ok I usually only give my opinion when asked.  I keep it to myself because I believe that people's business is their own.  A friend of mine has been seeing this guy.  Which at first thought is ok.  Well the thing is he is married and has a one year old with his wife.  WELLLL that kind of changes things, but still I am one to mind my own business.  She would want to talk about him and I wasn't rude I would just find a way to change the subject or step away because frankly I just didnt want to hear it.  Then one day she asked me, what was the deal and I told her nothing.  She said well you don't seem happy for me. I said well, she said well what.  "I said my opinion doesn't matter."  She then said yes it does what is it.  I said "well Im more or less sad for you because you have chosen to carry on with a man who is married and that seems ok to you.  She said well my relationships never end up right and this one is going good.  I let her know my point of view which is karma-what goes around comes around.  I said not to throw it in your face but you always end up with someone elses man then they leave you to go back to there girlfriends and in this case wife.  She then said she couldn't understand why I felt that way.  I said because I am a married woman and I am just thinking about if that were my husband.  She gave me the strangest look.  I then said what you do is your business but if you are looking for love that isnt it, you are still my friend but I rather not be involved in that situation at all, and I wish you wanted better for yourself because Mr. Right will never find you with Mr. Wrong standing in the way.  If he will do his wife this way what makes you any different...Respect yourself and this is the end of this discussion."  She looked like she wanted to cry and I promise that was not my intention but she was going to keep pressuring me until I said something and on this subject  and I couldn't sugar coat it.
