Are men capable of being with one woman, ama ni Jaba?

I ,29(F), just got out of a relationship that has left me mentally exhausted and questioning everything. My ex made me feel like I was the most special woman in the world. He told me I was enough, that I should be more confident, that he cared about me. He'd introduce me as his girlfriend and always initiated PDA. I was in heaven. But behind my back, he was flirting with other women, saving their pictures, complimenting them, and following them online like he was single. When I found out, he twisted everything—said I was invading his privacy, that I needed to be more secure, that I was the one with the problem and I needed therapy.

The gaslighting was insane. He made me doubt what I knew I had seen with my own eyes. Even when I confronted him, he stayed calm, as if I was the crazy one for reacting. Meanwhile, I was losing my mind, questioning my worth, and crying over someone who clearly didn’t respect me. He'd always say something like " Kenye nafanya ata sio mbaya. Kama unataka, enda tu but I promise you niggas out here are doing worse things" Is this true? Are all men like this?

Are men even capable of love and loyalty? Or do they just say whatever they need to say to get us to commit while they keep their options open? It feels like they always have one foot out the door, always waiting for something "better." I’d love to hear honest thoughts—especially from men.
