I feel like I should just avoid my childhood friend since she seems to be avoiding me anyway
Do you think your childhood friend is avoiding you?
Yes, she has changed for the worse recently. I don't think she is interested in me anymore
Avoiding a friend is sometimes what happens to all of us, you are not the only one. Friendships can sometimes drift apart, excepting that for what it is can be difficult. Finding fresh new friends can mean new opportunity, embrace that about new people in your life.
I think that's my plan for now.
It's good that you are willing to move on. I'm sure you'll make even better friendships in the future.
