Relationships are not about staying together because you feel as though there is no way out, or because you are in love. Although love is a logical reason to stay with someone. If he is being abusive in anyway its time to say goodbye. You must think about yourself. He is trying to manipulate you into thinking you are the one doing something wrong to take the spotlight off of him. Recognize your strengths and utilize them to make a firm decision. It could be one of the most important decisions of your life.

P.S That does not mean you have a mental health illness. If you simply asked a question and he blew it out of porportion then obviously there are some things you guys need to communicate better about. Do not think you are the one in the wrong here. Relationship=Communication and trust.
Without communication there will be no trust
