how do i .. break it ><, and go back to how it was b4 .. Options

[m&m]

ive been thinking abt breaking up wif my bf .. but the thing is.. its not that easy. i mean nofings wrong. i jus wana break it. like i still like him. but i jus dont really want a relationship. like i preferred it b4 we went out. how we'd jus flirt aimlessly and talk for hours .. i still feel im not ready and that im not mature for this relationship. i mean like i feel really nervous and stuff wen ppl are around us. i can never imagine us like those couples u c in skool making out. then theres ppl in my class who always laugh, make comments at us wen ever they see us. i always end up blushing, hiding .. ><
i just duno wat to say. i mean i stil wana b good friends. i told my friend that .. but she sed most ppl end relationships like that but they rarely do get back 2 how they were b4 they went out.
any tips?
how about
"hey.. u no how we've been going out for a while.. i was thinking .. that we shood just be friends.."
that sounds so retarted
