I can relate to that. Felt suicidal myself in a previous relationship at one point. Some women just want to destroy men - even if they've done nothing wrong. They're the crazy ones. Actually "crazy" is a too nicer description.
I've lived with two women in a relationship capacity before and both were total loons. Came across as normal to everyone in social gatherings but behind closed doors........
I had been living with the second woman for six weeks until she flipped one day. Punched me in the mouth when I had a tooth abscess. I left there and then and never returned. Haven't seen her to this day. Thankfully!
Took me years to get over their bullshit, predominantly from the first loon. Still haven't lived with another woman since these two. Sixteen years and counting......
