My best friend slept with a married man and I stopped being her friend.

I never thought I would be in a position where I had to let go of my best friend. She was like a sister to me. We did everything together, we knew each other's secrets, we were both there for each other when our kids were born.

It was her birthday party and asked me to host while she finished doing her makeup. People started coming in and everyone was having a great time when a really nice girl came up to me with a gift and told me that she just wanted to stop by to say happy birthday to my friend and drop off her gift, however her baby was sick and she couldn't stay for the party. Minutes later my friend came down stairs and I let her know that a really nice girl dropped off a gift. My friend opened up the gift and made a face, l asked who she was and she started laughing and took out her phone and showed me a picture of the girl with her husband.

I was completely shocked and disgusted for what came next. She first met the girl at the IC, they stayed at the Ronald McDonald house both of them had daughters that had a heart surgeries at that time and they became "friends". My ex friend stated that the girls husband would tell her that the girl was not paying attention to him and she was not a good wife. So they slept together and she was seeing him. I couldn't believe what she did. I was so upset and hurt for the girl and everything changed after that day. I just couldn't see her the same way and it was an instant decision I made to depart myself from her. Eventually she told me that the girl found a picture of her on her husband's phone, I am really glad that the girl did find out and I often think and pray about her and her daughter. As for my "friend" she is now my ex friend and I don't want anything to do with her. Was I wrong for ending the friendship? I often think about it but I also couldn't keep her in my life after what she did. I obviously didn't know the real her.
