They will ###$ with your head and lead to a myriad of things going wrong in your life. Many will try to break you if your healthy (as it is a challange). I wouldn't reccomend tangling yourself up with one. Keep them at a distance.
I'm not having a go, but do you really think this? I always thought the man I was seeing was just so blind that he treated me like dirt and genuinely didn't think he was doing anything wrong. He's always surprised (and incredibly aggressive) when I complain about the push/pull thing, like it's my fault for being needy, he's just really busy etc. I truly think he honestly thinks it's all my fault & he is completely blameless.
He's demonstrated aggressive behavior in front of my daughter, another child & a friend of mine. Not towards them, but at his "beloved" dog, who he attacked. My daughter detests him (she's a huge animal lover), my friend actually said she is traumatised by what she saw. He's never shown any violence to or in front of me. But his reaction to me getting upset at his treatment has always been quite aggressive. Not name calling, but swearing at me & getting really, really angry
Yet I still miss him
