Losing friendship

Over the past years I lost some friends due to trust and lies plus communication.and over those years I learned to just go out by myself like go to concerts by myself ,go take myself out to eat ect I started doing different activities like I’ve been taking dance class for fun and I’ve been loving it I gain some dance friends that I only see in dance but lately they been inviting my to hang out with them outside of class after my past friend experience im scared to have actually friends with the fear of reliving being disappointed and having this fear that something could go wrong and I could lose the friendships and end up in the same place I did with my past friends.
