Unexpected news

I've recently recieved some hmmm.. how should i put it... shocking news....
a friend of mine just told me that he is currently testing a relationship with a guy... my friend is a guy which means he is presently trying out the gay relationship... i was kinda of shock, overwhelmed that i did not know to react.. too shocked as i always knew him as a straight guy... so.. i really have to take some time to ease my thoughts and feelings about this matter... just too shocked... i've known him for a rather long time and it will take time for me to adjust myself to this news.. right now, i don't even know whether i should even talk to him abt this matter.. right now.. i'm just well.. rather disllusioned with the whole relationships matter... am getting a bit blur abt it.. i'm beinging to wonder.. will i be able to even find a half that i will be able to fall for, not even to marry ya know, only in love with, without the other party becoming potentailly gay.. cos these things just have become so unpredictable.. well, a lot of matters are unpredictable in life... and this is one area which i have grown rather disllusioned... maybe disllusioned is a wrong word.. i think given up hope would be more appropriate...
