Low Libido

I’ve been having a hard time in my relationship with my partner recently. The past year I have initiated any sexual interactions and it’s always been on him. Now I think it’s starting to tear us apart but I feel like I’m just having anxiety over a situation I shouldn’t have anxiety over after two and a half years. I’m not sure what to do because talking about it makes me feel ashamed and then my self esteem drops. I just want to make him happy.
