Another option is to include your girlfriend more in group activities rather than one - on - one interactions with your friend. This way, she'll be less likely to single out your friend for teasing. For instance, organize group outings or game nights where the focus is on the whole group rather than individual interactions.
I don't think it's a good idea in most cases. Your relationship with your girlfriend is about the two of you now. Bringing up an ex - love story might make her feel like she's competing with a ghost from your past. Also, some details of past relationships are private and don't need to be shared. If she asks directly, you could be honest but still keep it very general and not overly detailed.
If you suspect your girlfriend is cheating for the first time, the first thing is to stay calm. Don't jump to conclusions right away. Try to have an open and honest conversation with her. For example, you can say something like 'I've noticed some things lately that are making me a bit worried, can we talk about it?' Maybe there are misunderstandings that can be cleared up through communication.
Be honest but brief. Just mention the basic facts like how long the relationship was and why it ended. Don't go into details about the romantic moments you had with your ex.
Definitely not. These types of stories go against basic moral and ethical principles. Friends' relationships should be respected, and creating or spreading such erotic stories about their girlfriends is a form of betrayal and inappropriate behavior.
One sign is secrecy. If she starts being very secretive about her phone or where she's been, like always taking her phone to the bathroom or not sharing her location. For example, in a story I heard, the cheating girlfriend would never let her partner see who she was texting.
One story I heard was that a guy noticed his girlfriend was always on her phone late at night. When he finally got a chance to look, he found flirty messages with another guy. She had been making plans to meet up with this other person behind his back.
One sign could be that she becomes overly secretive about her phone. For example, she always takes it with her everywhere, even to the bathroom, and gets very defensive if you ask to see it.
