Seven months sober is just not enough time for the addicted brain to regain normal functioning.
One to three years is the more common time frame for cognitive functioning to return. If someone advised you that you could rebuild the relationship with mutual give and take in less than a year of sobriety, that person misinformed you.
And if you were told by recovering people that less than a year is too soon, then chose to ignore that advice, then unfortunately you are experiencing the consequences of not following the direction of people with more knowledge of addiction. (Most of us here have done that in one way or another).
If you think you still love him, and if he is sober and working a program, I would consider a suspension of all relationship issues and expectations and take six months off. Most codependents can't bear the prospect of a brief separation, but, honestly, only resentment and disappointment will be the result of trying to work out relationship issues with someone in early recovery. His brain is unable to meet yours.
