A guy I hav been talking to for 3 weeks randomly blocked me?

Anonymous
I haven’t dated since 2020 I met this guy 3 weeks ago and decided to give him a chance. we texted on instagram for the first 2 weeks he would only respond once a day he asked for my number and told me he don’t be on instagram a lot. I gave him my number our conversation was going well that day and then he just stop texting me for 3 days. When he did text me he text me from a different number and told me he has 2 phones and thought he was texting me on his main phone and was waiting for me to respond to his message. It didn’t really make sense to me but I didn’t question him and I just brushed it off and laughed about it later on that day he text me again i decided to wait until the next day to respond because I didn’t want to keep responding to him so fast when he has been taking a day or 2 to respond to me. when I text him the next morning i received a text saying message blocking is active but he has not unfollowed me on social media why would he just randomly block me was he never really interested in me?
