2 Situations Options

[alcohol_bandages]

Problem #1:
My friend keeps touching me where I don't want him too!
And I don't say anything anymore because even if I do,
he continues doing it.
He has a girlfriend.
I have someone who I like.
I don't like him like that.
He knows that.
It's getting irritated.

Problem #2:
I'm pretty much still great friends with all of
my ex-boyfriends.
Except for one.
We've been fighting ever since I broke up with him
because he wanted me to do things I wasn't comfortable doing.
A couple days ago I IMed him on MSN saying the usual.
"Hi!"
"How was your day?"
etc...
Then he starts ranting how I need a boyfriend
so I can leave him and this other guy alone.
(The other guy appologized and really had nothing
much to do with it)
He said some other stuff too,
but whatever.
Anyways, today he proceeded to go to my friends
(who he knows I talk to every day and would
take me over him)
and tell them he thinks I've gone out of my mind,
that I'm crazy, mental, nuts, etc...
So I call him out infront some people today.
And he deleted me off his friends list on myspace
(Which I was honestly planning on doing, but
he beat me too it, whatever)
I know for a fact he's going to go to even more people
and call me even more shit and try and turn people against me.
Which is going to cause major backstabbing and fighting
which I'm not ready for.

What should I do?
