I know not all

To be clear i know not all women. But its really starting to feel like all women cheat im tired of giving my all for someone and getting cheated on. The girls i used to work with would try sleep with me without shame while having a boyfriend. I honestly think i will never find actual love. 4 years she would tell me she loved me when two of them she was sending nudes to 12 diffrent men. It happens more often than not. why cant people just be loyal. I was broke all these years so i could support in her in life. I would give her lifts home everyday even tho it wasnt convenient for me. I loved her so much. its been 6 months sice i discovered the truth and i still feel sick everyday and struggle to eat. I dont want to feel anymore. im still with her because i cant bare the thought of her not being in my life. i think shes still doing it. i cant keep this up
