What is this personality?

A friend of mine recently told me his partner does not like me because I get attention when we all hangout, this takes attention away from his partner. His partner drinks alot and makes excuses why "Ive drank all my life"..."Ive had a hard life" Even makes excuses for the behavior....throwing tempter tants, will sit outside the house while I or even my friends sister is visiting and will refuse to come in, also talks alot but never makes any real sense?

Id like to find out this personality type, the needy kind so I can do some research for him.

An attention wh@re? Haha no seriously, I have no clue. You have to tell us more.

Ok for instance... Me, My friend and his partner all went camping. We got there, set up shop, then my friend and i decided to go down the river and see how fishing was... Well his partner did not want to go, so we left. We come back, to hae his partner PISSED off. all day/all night.. Wouldnt even come in the tent, wouldnt give a reason either. The plan was to go camping and fishing, everyone knew this before we left. as the weekend went on, his partner found things there to do that were interesting, and everything was just chappy! however, during conversations when i was not there, his partner does not like me becuz i get to much attention from my friend, apparently. When my friend goes to the store, his partner calls about 6 times (where are you, who are you with, when wil you be back)... Hes always turning around and asking him "are you ok"? out of the blue. My friend is 68 his partner 55... my friend might be 68 but hes not dieing for christ sakes....

the personality type is: Sulking dickhead who gets enjoyment out of ruining everyone else's fun. Refuse to go camping with her/him next time, go with your friend without her/him. S/He does not deserve your fun.

Forget the research, it's not your problem. Don't become involved. S/He's just another abusive old git!

PS: Can't tell if partner is a she or a he, if your friend it's straight, it's a she, if he's not, then it's a he....

My two friends are a gay couple...I tried to remaine gender nutral but apparently it did not work.

So a sulking dickhead? I wonder if they have a book on that personality disorder lol...
