Sorry to see the situation you are in Hannah. It never ceases to amaze me how some people can treat others and be so completly heartless. I would never claim to a "perfect" guy, But I shake my head at some stories I hear of how some men behave to women. It sadness me as I know how I could never do that and I am bitter that they dont deserve the love they have and abused.
As for the revenge story, that was good

I remember from many years ago, I was sooo close to trashing an exs car when I saw it outside a hotel, I knew she was in there with a friend of mine. I was so jealous beyond belief. Fortunately I had way to much to drink and ended up collapsing in the hotel garden instead! Good job really, she wouldve known it was me.
Anyway, hell yeah there is nothing better than a good vent. Vent away
Genuinely hope you get through this soon. Time will heal. Keep posting and take care.
