omg fate (or woteva)

this person has fancied me since year 8, i didn't realise this, but what they didn't realise is that so had i them. it all spilled out the other day.
their parents found out and hate it, my parents know and are cool. the person is really upset though, i feel terrible for them, but we have sworn to stay together.
this relationship could cause problems in my friendships, some are fine with it some aren't, i don't know how they will react when they know. i don't want to cause problems, hopefully they will be the same as before and everything will be normal still. i don't want to lose any friends.
