Blocking then unblocking someone 3 times what does it mean?

Asking this question for someone I know. Why would a guy love bomb someone then block them then a few weeks later start talking to them again? Then block them again and start talking to them again but each time it seems like he's changing for the good. Is he just afraid she'll hurt him or is it because he really likes her and his feelings for her are scaring him?
