My Boyfriend Passed decision hunt me every night…

I have now a happy relationship we text we see each other but before everything is perfect, He hurt me so much. He is my first boyfriend but I was not his first girlfriend so it’s hard for me to move forward on what he did. Everything started when we became boyfriend and girlfriend after being in a re relationship for 2 weeks he still had his ex. And you wonder how I found out, well she saw my profile and I asked him who she was and he say my ex…. This will take a while to tell, but yeah I’m still not over his passed decision.
