I have known you guys on here for a long time now and know that in general you are a very friendly bunch of people with good heads on your shoulders.  I have a problem that I was hoping you could offer your opinions on.

I have a cousin (by marriage and no blood relation at all). Ever since we were kids I had strong feelings for her. Over the years we have moved apart and don't see her very often. Maybe once a year. I have also been dating a girl for 7 years and she has a daughter who is now 9.

Recently my cousin and I have been talking on Facebook and I have a strong feeling of wanting to tell her how I've been feeling for all these years. What I really want to know by telling her is if it has been just me all this time, or if she shares these feelings.

I don't think there is any chance at all that I would cheat on my current gf, but I have had this question in my mind and these feelings for her for almost as long as I can remember. What would you do?

I am currently 25. male
