Egyptian id

have found out my Egyptian bf is marred he said he ist n keeps saying he ist.. but his id card when I scanned it from my phone it written he is.. he said he is only 2 me iv known him 12 yrs n we never been marred just had offi marriage n when we go 2 cairo now that I've decided 2live  with him in Egypt n get proper married he says my name will be added 2 his id ( he said he added marred yrs ago when I first met him n was going 2 move then to save time)
if he is already marred 2 someone else why ist their name on his id
but surely he just can't add marred 2 his id card just like that would he have 2 show marriage licence as proof which we haven't got
I trust him but now I'm starting 2 have my doubts.. is he marred 2 someone else or telling me the truth n my name will be added he knows everything that has been 4 the past 12 yrs will end if this is a lie/ cover up
hope someone can hrlp b4 I go
