Even though you are so upset that your husband has left, you have GOT to have some idea as to what his reasons are for leaving.
If you have a suspicion, or know that he has left because he has fallen in love with someone else, then, although it is possible, it will be difficult to make your husband want to come back.
However, if his reasons are because of something that you are doing, then it is a simple matter of figuring out what these things are, and rectifying them.
Do you take your husband for granted? Are you a very demanding person? Have you changed as a person? Any of these reasons would make your husband unhappy and fed up enough to want to leave, so make an effort to change it, and make your husband want to come back.
Although most husbands are quite happy to help their wives as much as possible, once this becomes a habit and the wife expects him to do these things, then he will feel that he is being taken advantage of.
It would be a much better idea to appreciate the things that your husband does for you, and to let him know how you feel.
Knowing that you appreciate all he does for you will not make him feel as if he is being taken for granted.
If you are a very demanding person, and are inclined to behave like a spoiled brat if things don't go your way, then do something about this immediately.
Remember, you are his wife and not his child - things are supposed to be fifty-fifty in your marriage, and not in your favor only.
Make your husband want to come back by letting him know that everything in your marriage is going to be fair from now on.
Then again, if you have changed drastically, and there is some way that you can improve yourself inside and out, then do it.
Maybe you have stopped taking care of yourself the way you used to.
This would be enough to put a lot of men off, and maybe your husband as well.
Knowing that you are going to be the person that he got married to will give you a good chance to make your husband want to come back.
