Girl just wants to be friends.

This ALWAYS happens to me.

I get to know a girl, find out she's single, I ask her out she says yes, then after a little while she just wants to be friends. This always happens to me.
In this case, she lived 45 min drive from me so its kinda hard to...

see her, but even so, most other girl says that in the end they just want to be friends and thats it.
It happens with most girls that I go out with... WHY???

What am I doing wrong?

it happens man,they just see its not working out for whatever reason,just be yourself and you'll find someone and eventually things will work out for you

When Your RelationShip Ends The other person gets a total new view of you,

Like my ex-boyfriend I when out for about 3 years and after awhile

it just hits you, I don't really like him like I use to

Trust me it's not just you it happens to a lot of Boys.

There is this Wonderful quote that goes...

Once You Find The Right Person You Realize Why It Didn't workout With The Rest

Soo True...

Not all girls are always ready to be in a relationship, you just need to keep on truckin', mate. You WILL find someone, the odds are not that high against you - you're an attractive guy and a nice one at that, judging by your interactions with everyone on this site.
