then the only thing you could do is wait till you go home for your vacation and now it will be the other way around...LET HIM TALK not you....STAY in one room together,lock the door so that there will be no interuptions, turn off both your mobile(dont turn off the light-loool)...
Just sit together look him straight in the eye and tell him to talk... SINCE YOU'VE DONE EVRYTHING, u do all the talking before ,TRY to let him do the talking now...
Nobody is perfect Qatariana, I am not talking even about him as womanizer... there are other reason and these reason is the one im telling you to brace yourself into...3rd party is not always the reason for a couple to separate, maybe somewhere somehow the feeling is gone and i hope not...
And if nothing helps with all our advise, guess i gave up then... just goodluck.... nothin more to say....
