I have friends......love me so much,they made a surprise party for me

Question

Which one is correct?

Whose Or who or whom or which?

I think the answer is who

Answer 1

Hi, 

Like your other question, to complete the first part of the above text the subjective pronoun "who" is needed.

Meantime, it seems to me that the second part (, they made a ...) does not fit that text unless it comes as a separate sentence beginning after a full stop (instead of that comma) with the capital T (They made a ...).
