So this post in based on my personal experiences and experiences from different close friends of mine. Thanks to Nataly J., Alejandra R. (my besties), JC and in some level to AJ for sharing your experiences and helping out to make this happen lol..

Who hasn't been in-love? We all know that the beginning of any relationship is amazing BUT not all relationships work out unfortunately. Yet, they will leave you good lessons and funny stories to tell about the "classes-types" of ex(s) there are ... Here we go with some..1,2,3.GO!
Ex-Karma
This is the ex that will leave a print in your soul like no other whether it is a good one or not so much. He/she will come back into your life unexpected particularly if she/he found out you're dating someone new. In some level it will be like a little ghost inside your head when you start something new.
The player - Cheater:
This person does not have a clue what it means to be FAITHFUL. He/she is with you but will make out or have sex with any other person (new-ex-"friend"-buddy). He/she says "I love you and it won't happen again" but it definitely will happen infinity times. When you guys finally break up after admitting how bad of girlfriend/boyfriend she/he is, that person will even cry to persuade you to take them back.
Too good to be true
Perfect relationship but it had to end not because of either of you but different circumstances that made you take different paths. You will always be friends and care for each other no matter who you are with or how long its been. Its memory will make you believe in true love
Mr Limbo
He/she is the one you like the most YET this person will not make a decision about make it exclusive. When the end is about to come, he/she will say the right things without drawing any line. Very egocentric even though he/she will deny it till the end. Even though he/she had almost everything you were looking for, like a good single lady/gentleman that respect themselves you say "bye bye" YET he/she will come back now and then to make sure if you are over it or not.
El boomerang
No matter what that person will never get over you even if they are dating someone new, engaged or even married. The relationship was so good that it left a mark in his/her life. That person always tells you how much they still care and loge you. You will always count on them. He/she will come back into your life from time to time but with goo vibes.
Almost the one
That person has everything you look for even though its not perfect YET you are the problem yes you! admit it! XD lol jk. That person does everything sh/he can to make it work but youuuuuuuu savage it. The relationship was going pretty good till some ghost from the past ( ex karma) makes you second guess some situation and be suspicious. In case the relationship ended, you really want a second chance because you know that person is someone you definitely don't want to lose and you will improve yourself for yourself and that amazing feeling.
The Psycho
That ex that will haunt you no matter what you do. That person will always try to contact you no matter how many times you ask to stop it. He/she will even haunt you new parent just because he/she want you both to break up as badly as possible creating whatever it is necessary for it to happen ASAP. This ex go crazy if he/she realizes "you are in a relationship". It is obsession not love!!!!
The Possessive one-The Owner
Whether or not you guys are together , you will always be his no matter if you agree to this statement or NOT! He/She will always be flirty and it is impossible to have a legit friendly combo with this person. no matter how hard you tried to just be friends.Therefore, when you have someone you love ( old or new), you decide best is to make that person EXIT your life permanently.
