Have you ever talked yourself out of liking someone to avoid your fears or being hurt?  When you have your guard up it is always for a reason.  Most likely it’s there due to past experiences.  There are times when taking a break from dating and doing some soul searching is exactly what you need.  It is better than going out on dates knowing that you will never have a second date due to your heart is just not into it.  We all need time to reflect and putting your dating on the back burner. I myself did this about 4 years ago and the benefits were amazing.  You whole outlook on being single changed.  When you are able to be clear about what you want out of the next relationship then it’s time to jump back into the scene.  So if your goals aren’t clear or your not over past relationships and the hurt that goes along with them just take a break.  You may consider relationship coaching or therapy.
