Men are not great communicators. They will let you assume something totally different from what they feel or want. He will endure rather than discuss. It’s only when he no longer wants the relationship that he makes you aware of problems often saying “this is what you wanted.”
Second, a woman should always guard her heart. It’s easy to fall in love with someone who doesn’t love you back. Some women go out on a couple of dates and the next thing you know the guy is moving in. What she thinks is a romantic commitment is in reality the guy looking for a place to stay for a few months.
If the relationship is irreparable, and he is really leaving here are two things you should not do:
First, don’t blame yourself. We learn what we really want by carefully examining what we had. If you try to keep him when he is set on leaving, you will only make promises that can’t and shouldn’t be kept.
Second, don’t spend your life worrying about it. The lesson from every relationship is “I can’t be everything to everybody.” Give yourself permission to live and love again.
