I finally told him everything

I have a fwb & I couldn’t take it anymore & told him I like him. He told me he appreciates me coming forward & that he likes me too but he wants to take things slow. He’s been hurt in a lot in the past & this is stuff he’s told me before we where fwb. He’s genuinely a really sweet person but there’s a lot that’s happened to him. Idk if what he said is a good thing & just give him some time or I need to move on. I’m willing to wait but obviously won’t wait forever either.
