Really love my boyfriend with all my heart but he wont make time to help me work this out?

We have been arguing lately about future stuff. He out of nowhere said he wants to hit a "freeze" button on our relationship and doesn't want to work on future plans yet.Which we haven't been together quite a year yet and we were just barely tossing around future "what ifs". He said he is freaking out and scared and now he is so busy at work so he says and wont make time for me. H owns his own business so I have no idea how busy he is but we live in the same town and I ha vent seen in but like three times this month! We communicate mainly on e-mails. I am so sad. I sent him like a really long e-mail saying I will let him go have his freedom if he wants it because I want him to be happy, I love him that much. He sent something back like Im busy and I cant deal with this right now, if i come see you i know you will want to talk about everything and i don't have hours to spend on this. I mean we need to have a resolution or we will never get better. If you dont have time for a girlfriend then what do I do? It upsets me so much and i even told him we can let things happen naturally. He just says well it will be years! What to do? I just want my boyfriend back.
