I'm so sorry you had to go through this experience, but it is just that an experience and a temporary one at that!

He sounds like he is confused and like he says needs space to think. Give it to him, you will be glad you did. Then if he does come back to you he did it on his own without prodding from you.

One thing you can do is set up an alter, like when someone dies. This will give you closure and help on a spiritual level. Put several pictures, a candle, and something of his. Then, when you get sad go to your alter and reminisce. Also, make sure all the memories and things of his are gone or out of sight except for this alter. It should be out of the way too, like in a corner.

Then, get busy, go productive things and things good for yourself. Don't smoke, drink, or be alone. Stay active and get enough sleep. Also, it really feels good when you are suffering from grief to volunteer. Think of all the people who need help (like in a school, nursing home, etc.) where you could help out. By doing something for someone else it not only feels good, it gets your mind off your own problems.

There are lots of articles on line about greif too you might want to read up on. Grief is a funny animal, it can visit when you least expect it too. There is a cycle to and everyone goes through this cycle differently. I've been there.

Be good to yourself and remember, there are other men out there! Good luck.
