Ang nakikitang kong nagkakaron ng problema ay ang nagsulat. Kung kaibigan mo sya, does it matter if bading sya? He is just another individual so just act naturally as before as if you were never privy to his "secret". If others found out later, that is never your concern. With regards to his girlfriend, I guess that is also not your concern - let your friend handle that. Based on my experience, I can smell that you also have a deep seated yearning for his girlfriend with the way you sounded. If you want his girlfriend, ask first your "bading" friend what his plans are viz telling his girlfriend about his "secret". If he plans to dump the girlfriend, let that be his initiative and let his plan roll so just be patient. Don't ever give an iota of hint to your "bading" friend that you also like his girlfriend. Let nature takes its due course. If there is a breakup, give it some months more before you make a move on the girl. For all you know, the girlfriend may even like the "bading" for being truthful and may even accept him for what he really is. Remember that there are a lot of "bading" who are married and even got kids. Pasensya ka na lang muna at sya ang ginusto ni girlfriend. There are girls who can manage a "bading" and may even let the boyfriend/husband have their guyfriends so long as the lady is financially supported.
