I am so confused

I married to a momma’s boy he is 47 still a momma’s boy!!! He told me clearly that his mom is his first priority and i come after that so i can not expect anything from him, since we got married we never go on a date never goes out alone never spend a quality time together his mother always sits between us, and the husband can’t spend a single time without his mom its really absurd! He don’t have any plans with me, i m here only for cooking and households and he just wants a child otherwise he has no reason to marry cz he is living his life with his mom. I am sick of it don’t know what to do , this man is obsessed with his mom. And depriving me from everything but has no realisation. I don’t want a divorce bcz this is not a solution they want me to leave, is there any way i can teach him a lesson then leave? Please help ladies..
