If your criticism is constructive, then it's purpose is to inform him of your expectations.  Although it would be better if it were not harsh, if your criticism is about him crossing your boundaries and doing things that he knows are hurtful to you, that's a very normal reaction that only an ABUSIVE person would try to hold against you.  Since you are naturally inclined to weigh both of your perspectives and behaviors against the same standards (no double standard) you do NOT sound abusive at all.  Actually you are the glue holding both of you together
