Although it spreads through poor hygiene having them is no reflection on how clean you are [Bit contradictory!].
Sorry but having worms s NOT a poor hygiene issue.
The eggs are microscopic. They live in dust, bedding, on clothes and of course on desks and tables in classrooms.

You need to read up on threadworms and understand how they are caught.
Brief summary:
The eggs are laid at night around the bum hole.
These get onto bedding if the person doesn't wear pants or PJs in bed.
If they touch the bedding or the eggs are on towels after they shower, anyone can pick them up on their hands if they live in the same house.
To be really blunt, you may not have 'caught' worms from your BF unless you were , literally, licking his bum!
Somehow the tiny eggs got into your mouth, either from his bed, his clothing, his brother's clothing, or their furniture at home.
In other words, his 6 yr old bruv might have infected you and your BF.
Unless his family are doing all the hygiene measure- and not just taking the meds- it's quite likely they will be caught again sooner or later.
They are a very common thing amongst all young kids at school.
But as everyone has said, why would YOU with OCD want to be with a bloke who rarely washes? Surely you are not a good fit as a couple?
And are you addressing your own issues?
You are overreacting a bit.
That's my lot on this- can't believe I'm writing about bloody works on NYE!
