@The OP, wow, the people that you have gotten involved with sounds as if they haven't matured mentally past 7th grade Jr. High (U.S 12-13 usually). So although it's nice that you try to stick up for the underdogs, it' not a healthy situation for either of you to remain in no matter what. Its' so much better to have no friends than nasty "friends" like that.

You both need to immediately severe ties with those nasty women immediately and make nicer, sane, and more mature friends. Try taking that person to a meetup group that you can both agree on going to. It's free to join. Go to meetup.com to check out new groups. Leave those toxic and immature women asap! Don't say a word to any of them. Just leave and don't respond to their emails, calls, or texts period! Tell that other person to do the same! They don't like or respect either of you! Trust me on that!
