Hey babe,
It sounds like you don’t know the complete story. Your mom and your friend’s dad could be friends or they could be working on a project together. Don’t stress over the unknown. You do need to talk to your mom about your feelings as soon as you can. The longer you bottle everything up, the crazier your feelings will get over this whole situation.
First, tell your mom that you want to talk to her in private. Second, tell her everything that you feel without blaming her for anything. Third, ask her to tell you what’s going on. Tell her (gently!) that you feel like you have a right to know since you are her daughter. Then, tell your mom that no matter what happens between the two of you, that there should always be open communication.
Before talking to your mom, write down on a sheet of paper everything you feel in one category and the next category write down everything you want to say to her. When you find free time, practice in front of a mirror everything you have written down several times before you talk to your mom. Practice makes perfect, since it will help you sort your thoughts out and it will take away some of the stress over confronting your mom about this problem.
