when love looks like a door mat

I love this girl. She's the first person i have ever loved so intensely that I want a future with her. I cheat and slept with me ex, told her, she slept with her ex and i stopped taling to me ex and she hangs out with hers all the time. We're not seeing other people and are jsut with each other but she slet in the same bed as her ex last night and i'm crushed. I love her and i want her forever but its not ok. Leaving her will kill me but how can i expect to be in a relationship with ehr when these things keep happening? When do u let go of the best thing in your life bc it could never happen? When do u tell someone that love is not enough? I just wnat her to call me and ask me to sleep over tonight because i just wantto hold her in my arms and imagine holding her forever.
