Should I stay. Should I go ? I’m so torn

I need some serious help !!!! Please ! I’ve been dating my boss for a little over a year. We have been going great. It’s to the point where I’m very much in love with him. He makes me so happy. He really is my everything. He is insecure. He thinks I’ had something going on with one of my coworkers. (Which I swear isn’t true ). He basically went out his way to rewind the camera. And saw me and my coworker had an Interacting. “KEEP IN MIND WE WORK TOGETHER “ in the tape it’ shows me and my coworker speaking and I got annoyed and walked away. 

SB; y’all don’t know me. But I have a very sassy attitude. My coworker is a bitch. He’s a bitch made man. He always has an attitude. Just the nasty. He is very arrogant. But he only acts this way with females. He doesn’t do this with the other men at the job.  

But what Should I do ? Should I just walk away from the whole relationship ? I really do love him. Just thinking about walking away is breaking my heart. 😢😢😢😢
