I hate my DD's GF's parents, and think they should have been banned from procreating.
In the year that DD and her GF (both 18) have been together, I have had to teach GF the following, because her parents have failed to do so:
How to set up a bank account.
To apply for a passport.
That is is not normal for parents to fail to take you to see a Dr when you have been in pain daily since the age of 12.
Find out which vaccinations she has had (answer; not many) and help her arrange to have the ones she has missed.
That she is allowed to have therapy with a therapist who is not best friends with her mother.
Shouting at one another angrily is not "normal communication" in a family environment.
She had no clue about any type of insurance - how it worked, what it was for.
Basic manners.
How to use a washing machine.
What "use by" and "best before" dates mean.
That it is not normal for a child to be subjected to "the silent treatment" by their parents.
That it is not normal for parents to have access to an 18 year olds emails, or to open their post, without consent.
That being autistic doesn't mean she's "a nightmare who needs to be physically restrained when she's overwhelmed".
That it's perfectly ok to need a bit of peace and quiet sometimes, it doesn't make her a "miserable cow".
And so many other things. This poor girl has been so badly failed by her DPs, it's shocking. She and DD1 have been together for a year, and they're about to head off to uni (same uni, different halls) and I hope it will be the making of her to be away from the toxicity of her home life. To her face though, I just have to say "that sounds tough, you can always call me if you need to", rather than "your parents are arseholes, leave and never look back!", as much as I would like to!
