Take a look at what's happening in nature. It's easy to see that every living organism on this planet has 2 fundamental needs and it is specifically designed to satisfy those needs, which are Survival and Replication. That's because nature(life) has an interest in its own Survival and Replication.

As people, we have other fundamental needs as well, but our long-term happiness depends upon the fulfillment of these two needs. So here's what happens: When you're in a loving relationship, you're getting closer to fulfilling your ultimate "mission" on this planet, from nature's point of view. So nature says "Good job, you're on the right track. Feel good and do more of what you're doing right now because it works." When you break-up with someone, nature gives you negative feedback in the form of feeling alone, sad, melancholic, depressed etc.

This mechanism lets us know if we're on track or off track from nature's point of view. It's nature's way of making sure that we're going in "the right direction".

So what can you do about it? Well, there is an almost magical thing that you can do in order to feel great and enthusiastic about your love life, even though you're temporarily alone! Few women know this secret and they're the ones leaving you the feeling that they're having all the fun in the world, even when they're alone. And guess what: it's that feeling of joy and abundance that makes a real man feel very attracted to you. That's what makes him want to be with you and be a part of your life. If you're heartbroken, you'll send a very powerful signal that will let a real man know that you're not the woman who's going to bring joy and enthusiasm into his life. So getting over the feeling of being alone is critical, if you want to catch a real man's attention.
