I hate it when my boyfriend eats around me
Are you allergic to his food?
I'm not allergic to his food. It bothers me to see him eating so unhygienically.
It is annoying sometimes to be around people who are messy eaters but you cannot let small things like that annoy you. You can let them know or eat somewhere else.
Yeah I get that but if I do that, I'll lose my control over everything.
It sounds like you want to be a controlling partner. That's not healthy for a relationship. If you're worried about control then your boyfriend will leave you to escape.
