Is it normal i really hate the ex but want to be friends with her boyfriend.

Haven't been with the bitch for 3 years nearly, and I genuinely think she's a terrible person (stole money from my bank account after break, froze me out of friend group, smeared my rep with other girls, told her parents I threatened violence against her which is, really pretty hard to disprove once the little girl's turned on the tears).

One mutual friend, a really decent guy and the boyfriend of her best friend, was trying to help both of us work it out but eventually shit got tired and I stopped talking to either of them.

Anyway, I love this guy, he's heaps of fun. We used to be really close, and went to college together. Used to dare each other to run naked in public through parks and in blockbuster. Just really funny cool guy into heaps of great music and whiskey and yeah. Still really dig the guy.

So when I moved state about 1 1/2 years ago I started a new life and deliberately forgot about it all, slept around a lot, had a lot of wild times, grew up a bit etc, got a new girlfriend and a house of my own. Everything's cool.

So the ex moves to the same city, with new boyfriend who is, SURPRISE, the diplomat from a few years back.

Now, I think he's great and I want my friend back so I invite him to parties and the pub and meet up with him in the city to check out the galleries n gigs n shit. But every second time the ex comes along and just is awful to me. I've had to forgive her for the past, but she's still a bitch. Snarky, and trying to flaunt their relationship on me. I can tell he gets uncomfortable with it but he's not incredibly assertive. It comes to a heads when I walk into my friends back yard after work and they're actually having an argument about him hanging out with me. It's obviously an issue, so.

So, should I just throw in the towel and fuck these guys off. This girl feels like more trouble than it's worth, but this guy is my long lost bro from home.
