That is very good that you could tell him what you want and what you miss, but I am not able to see progress as far as the relationship goes.

His response to your telling him you want to go separate ways in May and that you missed the things you used to do together... is to accuse you of over-reacting and inviting you to the gym, a place he enjoys is more of the same. He is dismissing your feelings and blaming you.

If you want something he can't/won't give, free yourself and start living your new life now.
