^ talk openly and stop hinting. Relationships are built on communication, if you’re not properly communicating and you find he refuses to communicate with you properly then honestly it’s time to seriously consider if this is a relationship that is worth staying in. If you feel like he’s not being honest with you then tbh I’d straight up say something like ‘hey I feel like you’re not being entirely open or honest with me recently, I’ve tried to have an open conversation a few times and you don’t seem willing to engage with that, I just wanna check that everything’s okay with you. I’m always here for you’ or something along those lines.
There’s going to be times where your libido doesn’t match your partner’s for whatever reason, that’s fine. But it sounds like you’ve got deeper issues in your relationship than that.
