Hello and welcome to e health forum.
From the description provided it seems that you and your boyfriend need to sit together and talk about your relationship. You need to let him know about your feelings in exact clear words, and also mention that how his actions cause discomfort and depression.
In case, he does not respond well, then the next step would be couple counselling with a good counselor or psychiatrist.
If that does not work out, and he does not mend his ways, and is still abusive, then you might consider alternative options, as it is difficult to change a person, who does not want to change. The need for change has to come from within.
I hope this helps.
