Ladies please help I dont know what to do

I have a boyfriend online and my friend dared me to tell him that I've been lying about my age the whole time, stupidly I took the dare and did it, after he said he didnt love me anymore, which even though I hadnt been lying to him that hurt so much because he had said that as soon as we meet he's going to propose and we're going to start a family. Now I wonder if he didnt ever mean any of that. After that I told him that I was dared to do it, after that he said dont talk to me the rest of the day and signed of msn.

I know I shouldn't have done that but should he forgive me, and what should I do to make it up to him, please help me.

erm yeah if you 'loved' him you wouldnt have messed with him like that. it'll just make him lose trust in people online in general.
