What should i do? i need advice & fast!?

Honestly, I would question his love for you because I understand needing space, but throwing the person that you are planning on spending the rest of your life with? I think he is thinking about breaking up with you but doesn't want to so he thinks that "space" might keep you guys together because he just can't handle it. Take a break from communicating with him just to get yourself over everything that has happened and then try talking to him about everything that you feel so you will know for sure where you guys are going with the relationship. Hope this helps :)
