A 39 year old man getting into a sexual relationship with a recently turned 18 year old and him trying to get her to live with him after just a few weeks of dating. He suddenly started spending lots of time with her, collecting her from work and taking her to his house the minute she turned 18 at the start of this year. For background, she is a vulnerable young lady and quite open with people about some frankly horrific and neglectful situations which happened throughout her childhood. Being left without food and having to shoplift to feed her and her siblings. Just a couple of years ago, she was removed from her Mum's care as her step dad was convicted for rape and SA against her and her siblings (she had to testify in court). He definitely knows about all this as I've been there with him when she's spoken about it.
My DP is of the opinion that the man in question is doing nothing wrong as 16 is the age of consent. Whilst legally correct, I think there's something very wrong in the thought process of this almost 40 year old man. I can understand it's a great ego boost for a middle aged man to get attention from a much younger woman. However, knowing that girl was abused just a few years earlier by a much older man and thinking it's appropriate to start a sexual relationship as soon as she turns 18 seems very predatory to me. Then asking her to move in with her after a few weeks as he can help her out financially, suggests to me he's looking to isolate her from her family and probably doesn't have good intentions.
My AIBU isn't whether all age gap relationships are bad, I don't think this. However, regarding this specific situation what do you think?
