DD is 15 and in year 11. She hasn’t had a boyfriend before and is autistic (high functioning). She met this lad who’s 18 and dropped out of college after a year he’s now an apprentice. He does seem a nice boy and DD is very happy being with him. I have spoken to her at length and I am convinced that he does want to be in this relationship- no coercion as such. My concern is that she is vulnerable due to her ASD and he is a few years older. Also, he can drive, drink, etc whereas DD is still classed as a child. He’s quite vulnerable himself- no sen but just quite shy, quiet, doesn’t have that many friends and I think he may be a little immature. I don’t really know what to do but I wanted to post for advice? Aibu to be concerned about this?
