My boyfriend and I have a list like that, by list I mean one celebrity cheat. His is Lana Del Rey, and honestly I'd be more jealous that he got to sleep with her and I didn't, but he'll never get with her, I think she's taller then him. Mine is Leonardo DiCaprio and I'm not a super model so I don't have a chance in hell.

Except for OP do you know of anyone else who actually went through with it? Even with the list being made together, it was always with fantasy in mind. Following through with it is considered cheating. Throwing away all thoughts of her relationship and sleeping with someone. Yep, still considered cheating.

If it's just fantasy, it needs to be made very clear that it is just fantasy, otherwise rare situations like this happen. If OP's girlfriend thought the lists were actual exceptions, and would expect OP to sleep with someone on the list if given the chance, then she can hardly be demonized for what she would probably see as luck. I know if I ever made one of these lists with a partner, I'd be ok with it if they got a chance o follow through and took it. Sure, I'd be jealous I didn't get the opportunity myself, but hey, I get the bragging point of saying my BF slept with Scarlett Johansson or whoever it was. Yes, it sucks if OP thought they were totally in jest, and his GF thought that they were fun unlikelihoods were still ok to follow through on, but that's what happens when you don't communicate fully.

As others said, even if it IS made for laughs, that needs to be said. Boundaries are to be set, and he set the boundary that it would be okay for her to do this. I'm sorry, but you set the rule. You can't just turn around and flip out when you actively participated and agreed to it. I'd say follow the advice of resetting boundaries to what you feel comfortable with. Don't just assume everyone knows it's a joke, for many they WOULD be okay with it.

He could always wait till she does something else that pisses him off and use that for it. Because he did make a list and to just randomly break up kinda seems unfit.

So if he can't get over this, he should be deceitful, and act like he is over it, and just start a fight at the next opportunity? If a relationship isn't working for you anymore, you're allowed to walk away, even if the other person thinks the reason is unfair.

#144 he can leave her if he wants, but the point is about whether he can go around telling all their friends and family that he is leaving her because she's a cheater. I would hate it if my bf slept with a celebrity. Then again, I would never make these lists with him, not even as a joke. And even if the dude DID mean it as a joke, if he didn't actually tell her and she misunderstood, then as others are saying that is more of a miscommunication problem. I wouldn't ever want to be in an open relationship, but I don't go around telling people who are that they are all cheating on each other. That's because I understand they consensually and mutually set up those standards for themselves. It sucks for OP, but if he said it was OK (and just assumed she'd know he didn't actually mean what he was saying) then he set himself up. If he feels betrayed and can't get over it, then sure he should end the relationship. But I think that it would be wrong of him, defamation of character, to go around calling her a cheater.

He just needs to stay positive

Don't think Charlie has much of a choice at this point

Thinking Charlie would be positive for many things.
