Guys, If a guy is scared of his feelings for a girl and pulls away what should the girl do?

So me and this guy were starting to get close and things seemed to be headed on the relationship path but then he pulled back all of a sudden and he seems to just be awkward and uncomfortable with his feelings and keeps pulling me closer and pushing me away. I’m fairly certain from things he’s told me that he's just scared to get attached incase he gets hurt but also has low self esteem and thinks he doesn’t deserve a good relationship. I’m just not sure if I should keep talking to him and engaging with him and trying to make him feel comfortable or give him space. He keeps telling me he’s distancing himself cause he’s got a lot going on in his head so I’ve given him space but we barely talk now and I’m worried that we’ll just grow apart so not sure what to do.
