In most cases, it's not okay. Your best friend trusts you with her relationship, and engaging in such behavior violates that trust. It can lead to a breakdown in the friendship and a lot of emotional turmoil for everyone. It goes against the basic principles of loyalty and respect in a friendship.
It could mean she's being inappropriate or she just has a flirty personality. But either way, it's not okay considering she's your best friend's girlfriend.
In modern society, views on lesbian relationships are becoming more accepting. However, sexual stories might still be considered private and not always suitable for public discussion. In many progressive communities, same - sex relationships are seen as equal to heterosexual ones, but there is still a long way to go in terms of complete acceptance everywhere.
It's a very personal decision. Some might argue that if they both feel a strong attraction and they trust each other, why not? But in reality, the risks are high. There's a good chance it will change the nature of their friendship, and not necessarily for the better. There's always the potential for one or both to get hurt.
You should stay away. Having feelings for your best friend's girlfriend is a tricky situation. Acting on those feelings could damage your friendship and cause a lot of pain for all involved.
No, it's not ethical at all. In a proper relationship, there's a commitment between two individuals. Sharing a girlfriend like that goes against the idea of commitment and monogamy. It also shows a lack of respect for the girlfriend as a person with her own feelings and rights. It can lead to jealousy, betrayal, and the breakdown of friendships as well as the relationship itself.
I'm not sure what specific situation you are referring to. But if a friend's girlfriend is acting in a way that seems inappropriate or'slutty' (a rather judgmental term), it could be a sign of many things. Maybe she has a different understanding of boundaries or she could be going through some personal issues that are causing her to act out. It's important to approach the situation with empathy and not be too quick to judge.
Well, dealing with the guilt is tough. You could start by reflecting on why you did it in the first place. Was it a moment of weakness? Then, you should consider talking to someone outside the situation, like a counselor or another friend who can offer objective advice. And of course, if possible, make amends with your best friend. But understand that she may not be able to forgive you right away.
