Hi all, just looking for advice and outsiders' perspectives on a difficult situation.
I have a great group of friends and we hang out together often. All of us childless and unmarried. A male friend from this group has been dating a woman for 5 years. We are based in Europe, she lives in the US and visits him for a month at a time 2/3 times a year.
She is 28 and he is 44, they met while he was living in the US too, but he had to relocate back to Europe a couple of years ago and they continued dating long-distance. She is planning on moving to Europe soon-ish to be with him and eventually build a life together (either here or in the US) get married, have children. He lets her believe this.
The issue is, we all know (well, all but her) that he has no intention to marry her, he does not want her to move here and when she is not here, he lives the life of a single man, uses dating apps and dates other women. We all know because he is open about it and sometimes he brings around the women he is seeing. He thinks he and his gf are too different and he does not want to marry or have children with someone who might want to move back to the US one day.
When his girlfriend is here to see him, he brings her to all kinds of social events with us and even to a weekend away last Summer with all of us friends. She looks at him with starry eyes and talks about their future together, while we all try to look away.
We are all very uncomfortable about this situation and we have spoke about it between each other. We have also all tried talking to him multiple times to tell him that what he is doing to her is cruel and selfish, he just gives us lip service, says that we are right and he is a coward and "he must make a decision soon". It's been 2 years of this so clearly he has no intention of making any decision.
I thought about talking to her directly to tell her what is going on, but based on how madly in love she seems to be when we are all together I suspect she might not believe me. I think he would deny everything to her. That would also end my friendship with him, although of course I have been debating internally whether I should even stay friends with someone with such little morals anyway.
What do you all think I should do? Talk to her? Mind my own business? Talk to him again and again? She is such a sweet person and she really doesn't deserve this.
I am unsure on what to do, but I think this is so wrong and I somewhat feel like I am complicit in his cruel game if I don't do anything.
