I know its hard not to get involved but I hope AJ will comes to his senses. I think you're right, he needs new friends and a new GF . A good woman doesn't flirt with her partners friends and friends most certainly don't flirt with the GF. The problem is, if the GF show any openness, his friends will try to move in. A good woman would say to the guy who came in his underwear..."get the hell out, what do your think you're doing". She sounds immature and doesn't seem to recognize proper etiquette, like not accepting gifts from exes.
