Mothers day !

Long story short ... am I wrong for wanting my fiance to spend mothers day with me ? His moms birthday is the day after and he always is doing something with her for her birthday. I just wanted one year where I can spend time with him and have him to myself. He works so much and we barely get to see each other 😔 and his mother and I are on the outs per usual. And this is not to spite her. I just feel like it would be nice if he spent time with me on mothers day and then for her birthday he could spend time with her .
