The shyt we preach in here isn't just tactics to look good bro. It's sharpening each other up to be men that live by their principles.
Meaning, you don't bush a chick to "win" or get revenge. You do it because she no longer has a purpose in your life.
You're hating on her man and talking about getting with one of her friends to make her jealous
Motherfukkers are in here with failed marriages. Dudes have fought depression after a chick hurt their self-esteem and self-worth. Brehs are grieving lost relatives while trying to get back out there and date.
But here you come every day ignoring everyone's advice to completely forget about this girl that doesn't like you and is only toying with you. Then every time you say you understand and we give you the benefit of the doubt for being young, you just come back the next day with a longer post showing that you're ignoring everyone's advice and just want to vent.
For you to not just feel like you have to get your self-respect back, but to do so on some "Hey, look at me. I'm with one of your friends now. Jealous?

" shows that this chick is still your sun, moon and stars and you're choosing to hold on to that pointless hope instead of honoring yourself and listening to what dudes who have been there and done that are trying to tell you.
And it's your call, but knowing that there are dudes in here fighting to go through some meaning of life shyt to change, yeah it's disrespectful to just use this as your vent session if you have no intention of trying to move past this girl.
You're a young man that can create life and elevate yourself to do anything on this earth and there's women aret there just waiting to find a man and treat him like a king.
But here you are following behind this chick for scraps and stressing over her, even though she treats you like her gossip girl, a free ride home and a self-esteem boost.
Meanwhile, she's on her knees after school every day turning her mouth into a cylinder shape and bobbing her head for a dude who only had to send a few half-ass text messages to get what you dreaming of
Love yourself my young, G. I don't know you but I know for a fact you're better than this. Get over this chick man.
EDIT:
I re-read your post. If you meant you're gonna get one of your homegirls to hook you up with a different friend and not a friend of the girl you like then I read it wrong and apologize.
But my point remains breh. Don't even take time out to vent about this chick or worry about what she's doing. You gotta develop that mindstate. Getting your jacket back should just be getting your jacket back as far as this chick is concerned. Nothing more, nothing less.
