Should I leave?

Hey guys me and my boyfriend have been together for 3.5 years. We rarely argue and our relationship is good but sometimes I find my self wandering. He’s in between jobs currently so he hasn’t been able to provide, and that has been eating at him. Today he told me that he used my private photos, that I sent only to him, to scam other people. He only did it last night, and he’s excuse is that he was doing it for us and only used 2 photos that didn’t “show my face” but I feel betrayed. I don’t know what to do I told him that I needed some space and time to think. Ik I’m worth more but idk I love him. I’m just hurt, I need some advice please.
