Most Helpful Guy
I agree with brandijo, a date night where the focus is not on what's been tearing you guys apart but rather what attracted you to each other in the first place would be a good place to start. I sitting down together and talking through this, asking him to explain what specifically about how you show love makes him thinks it is coming out of pity. Ask him to be as specific as possible, general answers won't get you far. Than bring up your how you feel and you truly are acting out of love. Hopefully this can give insight into what he has been saying while eradicating his how he views aspects of the relationship.
I wish you the best of luck.
