He changed his mind...

After 4 months of ttc my boyfriend just told me over text that he doesn't think we should be. He thinks we're not ready because he's still unsure of his future, career wise. I understand that completely, I really do... but that doesn't take away the hurt I'm feeling right now. After having a miscarriage Oct. 1 of last year, I've been holding onto us getting our second chance so tightly. Now he just took it away from me and it's making me so sad. I don't even know what to say or do, because I'm sad and a little scared things are going to be different with us now...
