I am a man. I have been in love, true love. And I have been fortunate enough to have the woman I love also be in love with me. And for almost 33 years we have been happily married.
I am having trouble understanding just what question you want answered or for what help you are asking. It sounds like you are in love (according to you) with a currently married man. Why would anyone wishing to give you good advice try to help you break up a marriage? If this is the case, you need to leave the guy alone. You have no right to go after him until he has separated. I don't care if you think you love him or not.
If I have misunderstood the situation or what you are asking, please clarify. Until you do, I expect you will get very few meaningful answers.
