Why are they both suddely acting so differently

So my best friend she told me to ask out the girl that is now my girlfriend. She seemed to really support me about it and said she really was happy that I did ask her. She also has her boyfriend but now she never really talks to me. She almost never talks to me anymore which is so different because before we had a great friendship. Always talking and hanging out and now its pretty much suddenly stopped. She never talks to me, texts me back, and never really wants to hang out.

Now the other other also told me I should ask her out my girlfriend but since I did she wont talk to me either. After all she was one of the one who most pressured me to ask her out. Now she wont even text me back. Barely acknowledges if im ever around her, kind of ignores me, and doesn't even look at me anymore. It couldn't have been something I did or said because since I asked out my gf she hasn't really talked to me

Thank you to anyone who answers
i just want to fix these friendships because I really didn't want to lose them

Could be that there is some rumor going around about you. If so it shall pass.

Or it could be that these people decided that they just didn't want to be around you for one reason or another. If this is the case the best thing you can do is let it be. Find new freinds, preferably ones that wont do this to you.

If you really want them back, you should just be sincere to them. Tell them how you feel about their friendship and see what happens. If they decide to make you a friend again then great. If not, then, unfortunately, there is nothing you can do about it.

Fact: Some friends are life. Some friends come and go. Others you never get close with. Some are out to hurt you for whatever reasons. True friends do not leave friends hanging.

Mend: Lean from the facts. Except it to be part of life. Realize that they are so many people in the world, you will meet and will make new friends. As the years pass, you will have people coming in and going in your life.

Living now: No one wants to loose their friends, right? All you can do is try to talk to them. Give them time. They might come back or may never. If they never come back, they were never sincere. "Drama" & "Jealousy" Are two Hateful gods that are overwhelming.

Hope this helpped and I hope you discover your "Sincere" Friends, soon.
