If he wants space you're going to have to give it to him. He may end up missing you more, he may end up leaving. Eitehr way, the worst thing you can do is to be more clingy - that will make him push you away harder.One thing you should do is keep in touch. By this I mean send him a letter or two every month letting him know 1) that you're still alive, 2) what you're doing, and 3) that you hope that he and his family are doing really well.You can throw in a"I miss those fun times we had together"line too, but do go too much deeper then that. If he writes a long letter about he misses you, you're back together. If not, just keep in touch, and date other men. It will take you some time before you are willing to date other men, but the pain will subside eventually.
