Giving a guy a break

Tori • 20 🖕 Hunter & Michael 💕
I'm in a relationship with a guy atm and we are currently on break but still together. His Ex is my best friend and still loves him, she's telling me I've completely lost him. My mother has read the text messages and ended up calling him and finding out the truth this is the complete opposite of what I wanted cause it's gonna make my situation worse now. What should I do ? I really love this guy and this guy is also like a brother to me as well as my lover. I want him back but I'm scared this has fucked everything up for me. 😔 has anyone been through this before and experience this or am I the only one ?
