Might want to take a bit more time between relationships. Try a year of no relationships and no hookups. See if you are a better judge of character by the end.

Be adventurous. Try a threesome..... Just sayin'

Just another 2 years and 364 days before you can chuck this loser!

Looks like this guy can multitask, so that's a plus.

Damn, that really sucks.

No one is gonna address the word 'snogging'?

So you didn't go and check at any point during those two hours where he was? Maybe it was a mistake, you know he got up to go to the bathroom and returned to the wrong bedroom.

Well you aren’t dating him so technically he didn’t do anything wrong

Sounds like you can’t choose housemates well either!

So, yeah, pretty much. Perhaps re-evaluate what sort of person you're going after.
