On the plus side you’re obviously extremely patient so at least channel the time into making progress with counselling. IMO though you should be prepared to declare you won’t tolerate a future where you’re this frustrated and unhappy, so ultimately you would leave or openly play away. If someone loves you they shouldn’t put you in this position in the first place, but they should at least try to respond if you get serious about it and try to work patiently towards an outcome that works for both of you. You deserve better than this! Everybody does.
