Ok, so I have a question, but I have to give alittle back story first.

So my husband started a new job and we moved out here to Colorado for a couple months until September. Its sales, and the company pays for the whole teams dinner (wives and girlfriends included). So one Sunday we went to brunch (sometimes it's brunch or breakfast) and we sat next to one of my husband's coworkers and his girlfriend. We had a lovely conversation, she was very nice, but I found out she doesn't live up there and just comes to visit him. Fast forward to tonight we sit with the manager (who pays for everyone's food) and the same guy walks in with another girl and they proceed to talk about how he does that all the time, with girls from tinder and his gf loves him. (Yadayadayada). My question is because I don't know her very well, should I not reach out to her and tell her something? I feel like I should because id want someone to do the same for me if that was the case. She just seemed like such a nice person and she's getting screwed over. The other guys that work with him wouldn't say anything, but I feel like as a woman, I'm looking out for her. Let me know guys please what would you do?
