Most Helpful Guy
Give it some time to cool down. Apologize for crankiness ( even if you don't think you were). Tell him that you wanted more... a life together etc and ask him if he wants you to leave. Tell him all your feelings and if still does not want anything then leave. Also, come up with solutions to the problems he mentioned.
You could send out a middleman to help him think... but give him sometime.
Most likely this is an anger issue fight thing. it should blow over and you should return your babe soon :)
