I am not taking you less seriously because of what you did. Two wrongs don't make a right though. You will both have issues from what has happened.
To be honest, I don't know which is more 'wrong' - getting together with someone because you have feelings or just doing it to even out the score. I almost think what you did was worse as there doesn't seem to be a whole lot of feeling behind it. How did it make you feel? Have you talked to your W much about what you did? I imagine she has issues to deal with on that score as well. Maybe she doesn't want to talk about it as she things what you did makes you on a level footing and you both just need to move forward from this point.
