This could all be true, but it's hard to evaluate these claims on their own. Not being involved in any way, all I can do is conclude that there is some friction in that community. It's possible that JT is toxic, it's possible that you are toxic, it's possible that neither of you is generally toxic but something about your personalities causes your interactions to become toxic, it's even possible that neither of you were toxic in any way but your impression of things after the fact is as-if Tunney had been toxic. Sometimes one has to stop and think about these things and figure out how to smooth things over, and sometimes it's not possible to smooth things over.
