If there was beef? Nope. Beef means physical or emotional harm.
One of my best friends was also friends with someone who hated me because she was jealous I was friends with him and I disliked her for spreading misinformation and I ignored her behavior most of the time but I was never scared to call her out. In the end she ended up being so emotionally abusive towards him trying to get him to stop being friends with me that he dropped her because of it. 8 years later me and her have a mutual friend who invited us both to her baby shower and I saw her a week ago. I stayed quiet and kept my distance and didn't say anything. She made a huge deal and sat as far as she could with her back turned and got jealous when our friend was holding my child and not hers 🙄 given it's not the same exact situation as yours because I grew up and realized the drama wasn't worth it especially if anyone was being emotionally abusive. She just always tries to come between anyone we are mutual with and I still dislike her a lot. I just don't put the stress on the mutual friend anymore about her.
If im friends with them to begin with they best be mature enough to put their differences aside when needed. So yes I can but I wouldnt force them to try to get along either. Id accept their decisions. As long as theres respect there should be no issue. And of one of them feels some type of way they should be able to come to me maturely.
