'candan ote cansin' sorry its got no turkish letters, it was wrote in a text. can anyone translate this for me please?

also, my boyfriend calls his cousin 'emmorğlu (i think this is how its spelt, i saw it on tv last night'), yet i cant find the word in any online dictionary so can anyone explain what sort of cousin it is because i know its not a direct cousin. thanks if you can!

candan ote cansin = you're the soul of my soul

emmoglu= emmi oglu= amca oglu= cousin (it means directly "cousin".. but sometimes you call your friends emmoglu to show some intimacy)

ooh thank you very much
