Repudiate all men in general only for some negative interactions is irrational and its root is in our prejudices taught since we were kinds.
Everybody have prejudices that we tend to have hidden which rise at moments of tough situations. Rational thinking is needed here, at least to distancing ourselves from these prejudices without denying them but prevent them from influencing our decisions.

Also it’s needed to work on understand a little the others’ behaviours. Only because a man try to attract a woman on the net, it doesn’t make of him a monster.
Then, it’s taking responsibility for our own participation in the even. For example, Jesyca, I think for you it was more a need to experience and experience has a reason. To learn from it. So, you will be more aware of how long you want to go, or find easier to detect red flags. Or even avoid any future similar situation. It’s your choice.

Complaining is good for nothing. You, Jesyka sometimes has a hard time recognising any mistake on your part and when you do it, you use black-white thinking a lot. This is a clear cognitive distortion.
I already mentioned -cognitive distortions-. I would rise this issue up with the student therapist.
