Im glad to hear that your hanging with a few friends and even quitting to strip to remove that influence and to get your mind of this guy. From reading these posts Ive noticed a gradual positive progression, although there is some things I would like to add to your thinking.
I do agree with uberinquisitive's post about how you projected all these insecurities and so on , to this guy, and because of that your validation to go on and exsist is coming from a Man! rather than yourself.
Really come to realize that your acting possesive because you want to be, not because you have to be! Deep down inside you know what your doing, but you allow yourself to do it. Like, still tormenting yourself by going on his myspace or his friends myspace. Understand, that by this continous behavior, your acting no different than before and these patterns will not allow you to grow and even possibly go back to your ways, because usually those ways are easier to deal with. But that will block your growth to move on to whats really more important, and that's Your personal development!
To my understanding if you worked at a strip club I am assuming that your an attractive person on the outside, and Im sure you were told this practically all you life. Now, I don't know you and I could be wrong, but, its highly possible that you were slowly conditioned or convinced to really believe this from an early start of your life. And all these years your reinforcement was externally..What about internally? How about reinforcing a new way of internal conditioning? Now, Im not implying that your just a pretty person that has no intelligence, you obviously proven that you want more out of life by being coachable enough to leave stripping and began educating yourself! I firmly believe that your on your way to a good start to letting go!. I wanted to also add some insight of what you mentioned too..
You said, you dont know what really makes you happy and dont know who you really are, and also, you didnt know how to figure it out and wanted to do more reseach.
Well, first off, detach yourself from everything that reminds you of this guy. In life, you learn from experiences, you dont marinate in them!! You need to break your patterns, Its gonna be tough start but if you really wanna let go, your going to need to do it, erase his myspace, throw his pictures away, take a different route home to avoid reminders ,etc, out of sight, out of mind!..Second an foremost! how about talking about School! Lets hear more of your progress in school!! The more you hear yourself talk about something you really desire, the more you will believe it!! its a proven fact! How else Con artists become really good at conning ppl? simple, because they believe their own BS! How else successful ppl become successful, cause they also believe they can attain their dreams!! Your no different, SO talk about school and more of it! what course are you taking up?, what do you intend to get out of school? what would you like to do after school?, what are your goals for going to school? FOCUS on you!!! everything else will come to you, as oppose you looking for it, do more for yourself and you'll see that what you want and who you are will become way more evident over time invested in yourself.
Im an entreprenuer, and like in business if I invest time and money into a business that isnt going anywhere and reaps no result, it becomes a total loss in many aspects. Or vice versa, if I go into a deal that turns out worth the time and money, then obviously, its a win-win situation. Same thing in a relationship.
My mentor once told me something very simple, yet Very profound! He said.. "Success is not something you attract, because success is something you become". Add value to yourself and you'll see that everything in return will be worth your value.
So one day, when you create that vaule you desire for yourself, and someone will notice your worth and where it counts, not physically, but internally! and that last's an eternity!
Good Luck, I hope this helped.
