Nic, I know how uncertain life looks right now and I know everyone says it is better to make him a little jealous. And the truth is he needs to understand that life will go on for you without him and you can still be happy. Do it at your own pace though, with whatever makes you feel good. It should all be just to make you happy, to not change him or with any expectations of making him come running back. you know well by now that such a return is only short stayed
