What should you do if your ex wanted space but now wants you back?

Many people find when they are in a relationship that things are moving too fast. They may even start to feel panic in the fact the person they are with wants more out of the relationship and perhaps wants to marry. There is nothing wrong with "stepping back" and getting some head space to figure out if this is the person you may want to spend the rest of your life with. It's a smart person that can step back and look at things rather than stay in the relationship and perhaps break-up in the end hurting not only themselves, but the person they love. Give the guy a chance, but be wary and make him work at coming back (don't make it too, too easy for him to come back into your life) and be sure he communicates his feelings to you so you understand the situation better.
