If it helps, Phunguy's W has just disclosed that she had multiple A's and I posted some comments I had read about this kind of infidelity on his thread.
A single A is hard enough to cope with, and only you know if you want to try and stick with the R, given what has happened.
Keep posting my friend. Others will chime in too.
