1. Inconsistency in behavior (hold-cold)
One day he is super sweet, kind and understanding. The next day he picks fights over nothing and tries to make you feel bad. This hold and cold method will play with your emotions and attempt to reel you in. He is in turn just manipulating you, and trying to control you while calling the shots. This is so unhealthy and toxic.
2. Silent treatment
When you disagree, instead of having a healthy conversation, he will give you the silent treatment and refuse to acknowledge your feelings. His idea of "fixing" things is to cut you out, until once again he will be ready to decide on his own terms when he wants to speak to you.
3. Gaslighting 101
To gaslight is to make you feel in essence "stupid". Like you have no idea what he was talking about, and that he meant something completely different. The conversation you apparently "thought" you had, never actually happened according to him. He will even go as far as to claim he didn't say something, that you know for a fact he said. This sort of word play, and technicalities that he might try to bring up, are a way of him playing games on you.
