Found out I have threadworms, for the first time ever. I have OCD about hand washing and hygiene so I was shocked I’d picked them up as I’m scrupulous about personal and home hygiene. My BF has a six year old brother and naturally came to the conclusion he is the source of the infection as primary schools are obviously germ central 
Asked BF about it and he said he’s had them a few times. The crux of the issue is he can’t swallow tablets as he hates the texture/sensation. So he’s never took Ovex etc, and as adults usually don’t feel the itching etc, it’s likely he has them. I’m distraught as this has made my anxiety and OCD flare up, I’m washing my hands 100+ times a day and they’re bleeding and sore and I’m furious BF won’t do anything.
AIBU to tell him he has to take the medicine (liquid version) as he will constantly reinfect me?
