After a Break-Up: The Three-Month Rule

After a break-up - especially a bad one - men and women have the tendency to want to find a replacement to make them feel less lonely. Yet the most important thing new singles must do is to take some time to reflect on why the past relationship didn't work, and figure out what to look for in the next partner.

The best rule of thumb is to wait at least three months to start dating again. Ideally? Wait six months. For some people, they don't feel ready to date again, but they do feel ready to have sex soon after a break-up. Though this urge can be powerful, it's best to say "no" to yourself as sex with someone too soon can leave you feeling even lonelier than you felt in the first place.

The number one comment I make to new singles is that they must mourn the loss of the past relationship, and the mourning process doesn't even START until you STOP trying to cover up the unhappy feelings - whether through sex with someone else, dating, or using drugs or alcohol to dull the loneliness.

I always tell my clients that this strategy hurts more in the beginning - to not act out on the feelings in any way, but instead to sit with them - but hurts much less in the end.

Breaking Up: Come On, It's Not War In Afghanistan

You might think breaking up happily is impossible. You and others might think breaking up is necessarily awful and that breaking up smoothly is a ridiculous notion. The truth is that a successful breakup is possible as long as you keep the focus on a few factors.

Focus on the friendship.
This is challenging if your ex cheated on you or betrayed you in some other way, but focusing on the fact that the two of you were once true friends and allies will make breaking up easier. After all, the reality is that you once thought this person was pretty cool, and nothing has changed the essence of that person is.

Remind yourself that you'll find someone else.
One of the greatest causes of bitterness during and after a breakup is the unconcscious fear that you won't find someone else - or that it will take forever to do so. That's B.S. What you need to do is stay optimistic and future suitors will flock to you. Plus, let's be honest: You're pretty cute, and everyone around you knows it.

Put the loss in perspective.
Sure, the end of a relationship sucks. No one ever starts something with the intention for it to end. Have a pity party for yourself, cry for a few days straight if it helps, and then move on with some good goals to distract you and refocus your attention. The end of a relationship is painful, but it's not a terminal illness or a four-year stint at war in Afghanistan. Keeping things in perspective will drastically reduce your anger, frustration, and bitterness!

Why Gorgeous Men Date Unattractive Women

Before we get into this, I must confess: this issue drives me full-on bonkers, the kind of bonkers that has me pulling my hair out and stubbing my toe at the very same time. I'm talking about hearing-Katy-Perry-for-the millionth-time bonkers. (Sorry, Katy, but your music really does push me over the edge).

Okay, back to the good stuff. I'm talking about the so-called phenomenon of a beautiful man dating or even marrying a so-called unattractive woman. I'm sure some examples come to mind, perhaps some famous or some in your very own neighborhood. In a nutshell, I can assure you that the goal should be to not even notice such discrepancies.

When I hear people often comment on how it doesn't make sense why a gorgeous guy would be with an ugly girl, it tells me that this person places far too much importance on physical appearance. In other words, because the guy is attractive, he is seen as more valuable; the girl, meanwhile, is seen as less than because she's not starting fires in the looks department.

If I see couples together and happen to notice that one is markedly more attractive than the other, I imagine that the less attractive partner is probably pretty damn cool and interesting. Ever spoken to someone beautiful, by the way, who doesn't seem to have much going on upstairs? Great, you see my point.

I spend most of my time counseling clients and writing about relationship issues, and the bulk of it is spent trying to help people see that the characteristics they should be focusing on romantically are the internal ones - not the external. I'm talking about how committed, honest, and kind someone is. As long as you're focused on this, you'll be just fine.

Bottom Line: The next time you see a gorgeous guy with a girl you believe isn't his equal in the appearance department, remember that everyone's taste is different and that what matters the most is finding someone who is genuinely interesting, someone who you actually care what they have to say! The truth is, with each passing year, looks will matter less and less to you - and that's the way it should be.
