yes people need friends. i need friends. ive tried the whole “get all your needs met by my romantic partner” thing. it works fine when times are good, but as soon as theres serious conflict or stress you need other people for support. your partner isnt perfect and neither are you, so in those bad times you share together you will see the worst of each other, and your needs wont be met. in time this breeds resentment and will lead to the end of the relationship. its a sad, lonely, empty existence going through life without friends you trust. you might not feel like it right now but eventually you will learn.
