I'm so sorry you're going through this. I know how frusterating it is! Sounds like you an he both need a little "intervention". Therapy for yourself is a good place to start.

My boyfriend doesn't "get me" either and it can make life so lonly at times. (I'm Bipolar and Borderline) He feels as though just giving me space is what helps and it has hurt us greatly over the years. (I need comfort and understanding, not a man that walks away from me) Truth is I would have ditched him years ago if not for having a 7 yr old son together. I wish you the best and hope you can get all the help you need.
