Maybe you should give him a week or so to think about things.
You should also think about things as well.
Then after a little time to cool off, maybe you can meet him and discuss things, how you feel and how he feels.
If you want to reconcile, then maybe consuling is a good place to start. A lot of seperations end up in reconciliation. Its not the end of the marrage by any means.
Take your time and think about things, give him a chance to do the same.
