Evil tease?

Ok first id like to say im only seeking help here because some girl has somehow managed to steal a piece of my heart and then she laughed about it and broke it to pieces.I have a girl already who i Love very much and been with for a few years but a coworker has really effed up my head, i never looked for this i was only trying to be her friend.
It started like a year ago when we began working together i would always bring up my gf but i was just friendly with this coworker and we had a fun time at work talking laughin etc. Then she started to wear really provocative clothing (but i would try not to look)and flirt with me in a subtle way but i knew she wanted me,saying sexual things in a nonchalent way,sucking on a choc lookin at me in the eyes etc telling me she loved me in jokey ways a few times touching me all the time on the arm when talking. I told her not to wear such clothes and to look after my eyes that helped for a bit but she came back with vengeance.
After a year of this pressure and comments like"dont throw that away ill lick it,ill lick it for you" i gave in and tried to flirt back but because i am a buffoon i wasnt doing a good job at it,the more i did the less she wanted me which is a good thing really because nothing physical happened and my conscience is clear now.
I arranged to take her to the movies but didnt follow it up,i think she was like pissed at that.

So anyway she was hot and cold for a while then one day she seemed upset again and i was growing tired of this whole act, so i tried to talk about our feelings for the first time,i said i felt there was something powerful between us she denied it.i said i cared for her and dnt want her to be upset cause i cant give her more, she denied it said she didnt want more.Said that she could open up to me and that im like a brother or something,basically she kind of laughed at me and treated me like a fool. Now i know she has told other female workers about this, i know she said to one "i hope he doesnt get the wrong idea".
We are kind of bk on friendly terms but im just so confused, she does seem to be the attention seeking type with other males she used to be fat and she has grown into a really sexy girl maybe she needs constant reassurance .
How do i turn the tables on her,she has nearly destroyed my life.

what are you wanting to do?

nearly destroyed your life?

you left her do it. you have as much fault as her on this, be a man, if you didnt wanted anything being firm was the way to go.

btw you farked up when you flaked on the movie thing. no need to turn tables on anybody. take it was a man, she wanted you, you farked with her twice(forgot that i read that you told her to stop flirting and basically rejected her) so she farked you back.

just avoid her, who knows you may have a psycho on your hands.

ALSO *** VERY IMPORTANT***

DONT sh1t WHERE YOU EAT

Maybe destroy my life was an exaggeration!

I see what your saying, i guess i kind of liked her from the beginning,but i was just trying to ignore the attraction and keep my honor but she kept pushing and pushing.
Also we were close buddies for a good year but it seemed she was just trying to hurt me real bad towards the end, she wanted me to hurt taking some kind of sick pleasure from it thats hard to take,especially when u cared for someone and thought they cared for you.

She is a bit of a psycho, kind of told me she hates men she had a one nite stand and has tried to make excuses for it think she felt used and dirty so she is deflecting all her rage on to me .

The small piece of my heart is healing and i will be able to give it all to my gf now, everything for the best !

So... Once again. What are you asking? Or are you just ranting?

Sorry,
I was hoping to get her to open up about her true feelings for me,
to make her want to just tell me.Maybe its too late for that ,i went for the serious route and it blew up in my face maybe the damage is done.
maybe i should just take the beating like prjav said

If a girl puts herself out there for you and you deny her its pretty much done. That's a really hard thing to come back from. She isn't going to tell you her feelings because you want her to now just to make yourself feel better. Take the hit and learn from it.

Ok dude heres the reason I ask. What I saw in your first message and subsequent messages is that you are seeking validation from this girl. When you could have had her you didn’t want her, but now that you cant have her and she has moved on you want her. Reality is this, YOU DO NOT WANT HER, you want the idea of her. Get over it dude.
You said earlier: “.I have a girl already who i Love very much and been with for a few years but a coworker has really effed up my head”
If you already have a girl and you are so in love, leave this chick alone and move on. Stop seeking her validation.

Me second concern is that you just want to get back at her and hurt her like she hurt you. And frankly I will have no part in that. That’s not what pick up is about.

You guys are right i didnt realise it until now,thats more or less the truth.I feel like such an idiot, im so sorry for this waste of a post,waste of time.

Thanks you have been a great help to me, i am just going to be her friend in the background, if she wants,i care for her but best to leave her alone.

Thanks alot for showing me the truth-i was being selfish.
