Unexpectedly Emotionally Unavailable

So let me get this straight. The only reason I let him in in the beginning is because he said that he is looking for someone to love and all those things that are in a relationship. Fine, and I was upfront with him too about looking for the same thing. This was all during lockdown. When the lockdown abated, we met 3 times. He wasn't as affectionate in person compared to texting. We continued texting every day and our texts sound like what any other couples would text each other. Now almost 3 months later, I communicated with him that if anytime he's into someone else, he should let me know and we must part ways. So that's out in the open. His reply to that is telling me that he needs to be okay with himself and heal from his past traumas before even looking to be in a relationship. I'm not sure how to handle this situation or even what healthy train of thought to have? Because it's a completely new situation to me. I'm also tired / lazy to look for someone else because of all my past hurts. I thought I did the right thing by purposely not starting anything with emotionally unavailable guys, but now here I am. What do I do?
