Is it normal that my relationships last less than a week usually

Shouldn't you be colouring or something..?

Lmfao ^ matiu

Can't really call them relationships now, huh?

Why do they end before a week?

Not unless you're in kindergarten

well, first of all, a week isn't a really long relation ship.
like allot of people said.
what you should do is build a friend ship with some one you really like.
and if it works out ask them if they truly like you. and you never know,
they might actually like you.
try to build a relation ship base on different things you like.
if they like some thing that you never tryed, give it a shot.
it might actually work out for you.
I"m not a huge expert on relation ships on account I never really had a real one. but if you find some one you like, just like I siad a few minutes ago.
build a friend ship then ask. it might work out.
good luck!

Depends how old you are.

I'm really shy around girls which doesn't really help

How and why do they typically end? Have you ever wanted something deeper? For me, the best part is three to six months in. When you're really comfortable with each other, but still can't stop touching each other and being affectionate.
