I'm thinking of my mom influencing me to break up with my girlfriend and ending my relationship with my best friend.
Why does your mom want you to cut off your relationships?
I am not sure why. I do not like her advice at all.
Since romance is such a personal choice, it is not a good idea to have your family influence your choice of a partner. While your mom may indeed want the best for you, you do not always have to agree with what she suggests, especially if you feel strongly against it. It's okay to act in your best interest and not give your parents complete control over your life.
You are right, I just want to chill. My life is good and I don't need advice from anyone.
I understand that you want to be respectful of your mother. But there does come a time where you need to do what is best for you.
