Why is he acting like this??

Ive been talking to this guy for a month...like literally 7 times a day and an hour- 2 hours before bed..and there are so many thing i love about him and ive really fallen for him and it terrifies me because i dont wanna get hurt. i brought up a relationship to him and he told me he really liked me a lot but he doesnt want a gf right now(he recently got out of a 4 yr relationship). i asked him what he wants and he said he doesnt know..i told im not gonna be a hookup for him and he said he doesnt want that and he is not looking for a hookup. But after the "relationship" talk , he has backed away and doesnt call or talk to me as much. So its not what I expected and I dont know if i should continue to be his friend and risk getting deeper and deeper feelings for him(i know i will) or should i save myself from heartache and just cut all contact with him because he has made it clear he doesnt want commitment right now?? Im confused and Im terrified because i know it sounds crazy, but i feel like i could fall in love with this guy.. its a feeling hard to explain
