Can I control my boyfriend's life?
What would be the purpose of controlling your boyfriend's life?
Because I want everything he does to be about pleasing me and making me happy.
Being that controlling and selfish in a relationship is not healthy, and will make your boyfriend unhappy. If you want to make suggestions to your boyfriend, that's completely fine, but don't force him to do things.
Screw you. You don't know what it's like to be in my position.
Regardless of what your position is, there's never a reason to be so controlling of your boyfriend. He is his own individual and should be able to live his life how he wants. You should be more willing to let him make his own choices.
