**Feline, your post has stimulated much response, which is great...some are silly but most I think are very straightforward and sincere. My reply here is to respond to you 2nd question of "How did that turn out in RL?"
The method or means of finding love is not within its way of finding us. Your giving love to another without expectation is a true love; their response is not guaranteed, and need not be if it was approached without that expectation. Granted, we would probably like love to be returned in kind, but really when it comes down to it....its in OUR loving another that really is the most fulfilling. My RL partner and I met in chat, now in the eighth yr. of our marriage.
I agree with those here about the importance of honesty. This will be discovered very soon after a RL meeting or even within SL. However, any "committed" relationship will test your love, that love is continually tested the entire time you are inside that commitment. This is the nature of promise and personal integrity. Your being 'trusted' is directly related to you keeping your promises. To break a promise of any kind will hurt not only the one you broke that promise to, but also to whom you made the promise. The guilt that lives inside a broken promise can also lead to depression.
I am not a Bible toting preacher, but I have not discovered anything that expresses “what love is” better than the following:
"If I speak in the tongues of men and of angels, but have not love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but have not love, I am nothing. If I give all I possess to the poor and surrender my body to the flames, but have not love, I gain nothing. Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres. Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away. For we know in part and we prophesy in part, but when perfection comes, the imperfect disappears. When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put childish ways behind me. Now we see but a poor reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known. And now these three remain: faith, hope and love. But the greatest of these is love." (1 Corinthians 13:1-13)
Notice that the above emphasizes "but have not love". The very best I can do in life is to love others; if I were to expect it...do you really think it would be real/true love? Therefore, it will turn out however it turns out, regardless of how or where you have met.
Separately, I'd like to share my views on your first question, which might stimulate all kinds of responses, but, nothing ventured is nothing gained.

Please see my next post on "Have other people found love on SL”.
