How to be a better cook ?

My boyfriend kind of makes fun of me because I am not a good cook. It hurts my feelings. I try to cook and I google recipes and I try my best. The one thing I don’t know how to cook is meat ( chicken, steak, pork chops, ect)

When I stay at his apartment With him he says he wants a cooked dinner when he gets home from work.

I know he has told his aunt and uncle that I’m not a good cook and i think he tells his friends. Its embarrassing.

Any advice ?
