My suspicions were right !

I had a feeling for months that my boyfriend was cheating on me .. and I was right. Recently found evidence on his phone. The girls name was saved as a contact in a guys name !! I called that b*%$h. And she denied everything .. I know the difference.. I seen messages and FaceTime calls to each other. My heart is broken into a million pieces .. I cannot believe I'm dealing with this again. My ex cheated on me. Took me forever to get over it and move on. And here I am again .. what's next ? Do I forgive and forget ? I don't think I will ever trust him again now :( I uprooted my life from hometown almost 5 years Ago. Left everything behind .. if I walk out now. I have basically nothing. Not even a car to drive .. my life is falling apart 💔. I don't see a way out. Yet !! If I stay. It'll drive me crazy ! I don't think he has her number deleted off his phone. .. that can only mean one thing !? So broken 😞
