Live your life and she will get over it.

Your friend will come around. Maybe she has protective instincts over you and that causes her to have more worry than is needed. Just remember shes your best friend and that she will stay by your side. Trust your instincts. How does your new man feel about this?

You could ignore your interpretation of the situation for hers...why not let her decide what your favourite meal/colour/movie is too?😉

She is just probably looking out for you and don't want you to get hurt or make any wrong decisions.

Did he cheat on you or beat you?

Sounds like she's concerned about you moving on quickly.
