Awwww...Sweetie~
You are so confused.

"I'm just afraid that I'm creating hatrate inside myself annd I don't like to be jealous and angry person!"
Please know that you are NOT creating hatred inside yourself. You are far too kind and compassionate of a person to harbor hate.
I am confident that once Aaron and any of the others are removed and their negative influencial remindings have been gone, you will no longer need to even question yourself if you are the jealous or angry person.

"Not sure if my feelings are valid...."
Your feelings are VERY valid and will ALWAYS be AS important or even take presedence over all others. Try not to ever think that your feelings are second to none.

"I value every individul"
With that statement clarifying who you ARE as a person, that alone dictates the very fact that your feelings are valid, (which is why I said that you sound so confused).

"I feel bad thinking that I don't really like them....I don't want to be that type of person"
You are FAR from anything even close to that type of a person.

"can't be friends with everybody"
True. BUT, you CAN be friends to who is most important...YOURSELF! And from the sounds of it, you ARE!

"they are nice with good heart, but I'm not into them"
Absolutely NOTHING wrong with that. That does not mean that makes you a bad person. It ONLY means you know what you want for yourself AND you strive for that....(something that many people have yet to learn how to do for themselves).

"I might ask him to remove my photo from his facebook"
THE best idea yet...Aside from dumping his hurtful hiney!!

I commend your strength and resilience, and your love for yourself.
You are a beautiful person, Marjan.
Keep your faith and true to yourself and you will see that good things do come back to you.

With love, and take care..
