Me 22M Bf 25M - Need to ask some questions

Hey y'll,

I am [22M] and my boyfriend is [25M]

I am in this relationship for more than 2 years

Just wanted to know your suggestions as I have a boyfriend but he stops me talking to other people (20% of his focus) and mostly he don't want me that I go out with any new friends or old friends?

I dont know why?
