Is it wrong of me to let him know that I am very committed to him, but I do not accept abuse?
Totally right to do this, but you will need to practice boundaries to address this
And is it wrong of me to let him know that just taking medication is not going to solve his issues, that he needs regular counseling to work on his emotional state of mind?
Probably a waste of time he needs to work this out himself. He will just take it as you being controlling and invalidating his decisions.
I want him to first stop his angry burst outs, he wants me to first have sex.
Again boundaries, and you have a right to do what you fell is right and not coerced into anything
Is he able to validate my feelings at all?
Probably not, you have to learn to believe in yourself. validation needs to come from outside support. The value of valuation is only as sound as the mind that provides it.
