Should I drop this guy?

Hi, I went through the list of forums and decided this was the most fitting for this topic so yeah, move it if it's in the wrong forum x:
*warning, lots of text*

I've pretty much been friends with this guy since we were in our level 20s, questing and helping each other to our late 50 levels, But latley things have gone a bit pear shaped. We just had another argument and i'm beginning to wonder if i'm seriously wasting my time being friends with him like my guild says.

I made my guild at level 43, he joined another big named guild which I advised against and he left later, like I knew he would. He decided to try out my guild and I granted him highest position and his girlfriend, a marshal. My guildies didn't like him at all and he didnt like them. One of them joked about him cheating on his girlfriend, he got upset and left.

He actually threw a huge drama over it >_> I understand what the member said was insensitive but he took the situation a bit further than needed. But there's a few reasons leading up to this. Everything I decided i'd get for myself, he and his girlfriend had to get before I did.

At first I spent hours helping them get their rare bunny pets, He needed 5 because he wasnt a veno obviously. I decided i'd get myself a bear cub as the rabbit really wasn't to my taste. I log on the next day and it turns out his gf also has a bear cub. They began rubbbing it in my face how this group of people helped them get it and there was also no mention of helping me get mine.

Later I decided i'd get myself a panther, I begin farming money and saving. Next day, they have one. They rub it in my face too. Same with zen clothing. Later I sold my panther and got a different flying mount instead. He wants one too. I give him around 750k and he buys himself a flying sword. At this point i'm dead broke and he's still rubbing his expensive sword in face. I recall plenty of times when he was dead broke and I gave him money so he could continue levelling.

I decided I didnt like my veno so I make an archer. He said he'd help me out. His high level buddy comes along, they start duelling and i'm ignored. COMPLETLY ignored. He logs out later and dosen't even tell me he's going. Later on when he "helps out" he's flying above me with his gf in his arms smooching and blabbing away about how much they' lubb each other forebber'
and then has the nerve to complain that I meditate too often.

I also still have a long list of bosses almost filling up my quest log and i've asked for his help a million times but keeps going on "Oh yeah my guild helped me kill all the bosses I needed last night ect ect" ...We used to always help each other kill bosses....

I recently had a conversation him which caused this stupid argument but I kinda thought is he really worth being friends with anymore?

him "you should join [guild name] for TWs next week and see what they're like"
me " ok o:"

him "you'd probably be in the 8th squad though, based on power and level even though we're about the same level while i'm in the top 4"

me (A bit offended, i've been adding nothing but magic for the past few levels) "Barbs latley have been having trouble keeping bosses aggroed because I do too much damage..."

him " Lol, (my name) Our tanks have aggro skills, Your tanks are just normal barbarians. The tanks we use have actual tanking skills"

me " =______= All barbs get tanking skills, what's so special about yours? the fact they're in your guild?"

him " No, You arent listening MOST (EFFING) BARBS DON'T USE IT, Our babrs level up those skills so they can be god damned tanks"

me "(And 'normal' one's dont? >_>) Oh alright, so every barb that isn't in (your guild) aren't good barbs, i'll let them know that. *leaves squad*

I told my guild about this latest fight and they're just telling me to forget about 'this loser'
I've never been good with people, so should I? .-.
