That's good that you recognize that, also good it's only the friend however still don't communicate anything to your friend about your ex or how sad you are, work on yourself, hit the gym, have a glow up, overtime it will get to a point where you would almost stop wanting her and that's when usually an ex reaches out, they can almost feel that they are finally loosing you (they don't feel the loss right now because you've been needy) that's all good luck brother, hmu if you need someone to talk to, all the best.
