you make me happier, funnier, better when we are together

Thanks in advance.

Birlikteyken beni daha mutlu, daha komik ve daha iyi yapıyorsun.

ok to make it clear Birlikte-y-ken means when we are together? i can´t see anything referring to "we / us".... so how could i say when they are together?

Good point. I know it with my exprience of speaking Turkish all my life If you want to say when they are together:

1)onlar birlikteyken

2)onlar birliktelerken

3)birliktelerken

You can say any one of these.

thanks gokuyum i know my translation questions are always doubled but its your fault you always answer

More detailed explanation:

You see the predicate is yapıyor-sun. It has this  personal ending "-sun" for the second person singular. So it means it is "you" who does the action. So you is the subject. Now lets find the object. It is ben-i. It is definite object because it ends with -i. So object is me. Now birlikteyken means "when together" There is no reference to any person. But I know that subject is you and object is me. So you + me = we. Now I know that only reasonable explanation is "birlikteyken" adresses "we".
