ds has aspergers, dyslexia and dyspraxia
he is really good friends with lots of girls, they seem to love his company
he met a girl on line and for months they have been getting on great over the net (web cams hooked up, the works)
he has recently met her and since then she has said her mother doesnt approve....now im not daft, but he is...naive to say the least
he wont accept that it may be because in the flesh he doesnt wash, shave, keep tidy or care about his appearance or personal care in any way what so ever, or even that maybe in RL they just didnt gel.
he is 19 but quite immature
do i just keep out of it? i want him to find some happiness but i cant see what type of person would accept they way he is (geeky, unkempt, scruffy, untidy, nocturnal, stubborn) but he has some lovely qualities aswell.
ive asked DD to try and speak to him (she takes personal grooming very seriously! but is 5 years younger) but he isnt willing to take advice off a 14 year old girl...
or me
or DH
he is insisting its simply that her mother did not approve (this is after a year of talking on line) 
how do i broach this? please bear in mind that he is not simply lazy, that he has special needs, but is also an adult. i want him to be happy.
