Girl problems

La

Okay so my sophomore year of high school my best friend and I came out to each other. In our friendship we always knew there was something else there but neither of us said it. We dated on and off for about a year and a half. Then we both got into other relationships and cheated on our respective partners with each other and different points. We broke up with them and have been on and off since. Recently we both talked about how we are in love with each other but didnt know the other felt the same. I get extremely jealous a lot and Im not sure if its toxic or if i should trust her and keep being a thing with her. Help what do i do
