Source of jealousy eh girl?
You know, i've heard that girls are innately posessive. So even though you two
are just good friends, you may just be jealous that "hey, that
girls cuddling my good friend!" and feel well, maybe lost control
of the situation or something.
Nothing to worry about in most cases.
Coming from a guy's view. I think its normal. For me to see a good
friend, be it guy or girl, hugging or kissing a stranger, wow, i'll
tell you i would get jealous, even for a little bit.
Wait, just looking at strangers alone do that... so well, you get
my point.
