when love fades, should i fight for it? (part II, text theads)

is he manipulating me? backstory: I told my bf of almost 2 years that I am going through a season of doubt ever since he cheated on me (downloaded a dating app during our break [not breakup] and was texting her while he was texting me even though we agreed that we loved each other and would continue dating when he is feeling better from his depression. they never met up) and things were moving too fast. he blocked the girl that he cheated in me with when I asked him to, and he went ahead to unfollow all women on social media who posted half naked pics of themselves. we started dating 2 weeks after he cheated and he bought me a promise ring the month after. I got concerned with how i felt like my love for him was not like how it was before he cheated. i almost felt numb. one day, he got upset with me and I did not even feel phased if got angry and left me. he stayed of course, but I felt that type of numb. so i got worried i was feeling this and wanted to tell him so we could work through this together. he was impatient and upset with me, then got sad and said that he was a monster for cheating on me. then he said goodnight and hung up on me. we texted this morning trying to make one last attempt to talk and make things right as I am on the verge of breaking up. is he manipulating me?:
