Input: To give a little backstory, my girlfriend (who I’ll call Ann) and I have been dating for almost a year now and we’ve been going pretty smoothly. I introduced her to my friend (who will be called Bob) who introduced her to his boyfriend (who will be called Jim,), everyone got along well. One day I get a text from Bob  saying that Ann and Jim are over at his and asking if I want to come up as well. I reject the offer as I was pretty ill that day, he sent me a few images of them having fun together, she texted me a few times. I had gotten a text later from Bob showing a picture of her T-shirt pulled downed a bit showing her bra, I texted her asking if she was alright and she replied that Jim and Bob were poking her breasts and ass and that she felt a little uncomfortable (in case anyone asks, they were bisexual).

Fast forward a few months, Jim and Bob have broken up and we all, more or less, cut off contact with Bob and Jim and Ann are best of friends. Now Jim personality is very flirty and that can make me a bit jealous at times, though Ann never flirts back. I was texting her one day and I ask her “What’s up?” And she replies “I’m on the way to [insert my hometowns name]” I ask her what’s she’s gonna do here as she hadn’t texted me beforehand to ask if I wanted to hang out, she said that Jim and her were gonna hang out and asked if I wanted to come along, I responded with a simple “Yes.” They both come of the bus and I greet her with a hug and say hello to Jim (who had also came on the bus) and they two immediately got to talking, I just kind of floated around feeling a bit like a third wheel. We eventually got to the town centre and I told them that I was gonna run home quickly to get a coat as it was a bit chilly and for them to wait there. When I returned we continued walking around. Fast forward to the end of the night, I got into a small argument with Ann about drinking, she felt like I was a bit too restrictive with it (I don’t drink) and basically didn’t want her drinking because she doesn’t handle it well. I stormed off back home. I apologised next morning through text and admitted that I had been a massive asshole. 

Fast forward to about a week or two ago, I had, more or less, come to the conclusion that Jim didn’t like me very much, I talked to Ann about this and she kinda confirmed this. We basically talked about Jim for a while, and that I especially disliked him for showering her with compliments. She revealed to me that after I went to get my coat, they had talked about me (he had basically said that I seemed a bit insensitive), and after the argument over alcohol he had encouraged her to break up with me (she didn’t, luckily), and I have grown to have a big disliking of him. Am I an asshole for wanting her to stop being his friend?

tl;dr - My girlfriend best friend poked her ass, flirts with her, dislikes me and encouraged her to break up with me.
