I've been talking to a few girls. Nothing serious. But I can tell the affair messed me up. If a girl seems interested and excited, and then doesn't text for a while, I start getting worried and assume she doesn't like me. I easy never like that before.
Guess I'm still just nervous.
I politely disagree Collin, you're not yet healed enough to put your fears aside. None of us ever lose that fear really, we just learn to live with it, accept it as part of us, and decide that the risk of being hurt again is so much less of a defeat than allowing opportunity to pass us by, unseized.
You learn to be a person of opportunity, not of fear.
You are not there, yet. It takes time, introspection, and repeatedly stepping out on that skinny branch and experiencing failure until it really sinks in, that's assuming your mind is fully clear of your ex to begin with.
Some men (and women) believe that their key to healing is finding another to make them feel whole and validated, maybe even healed. I fundamentally disagree with this, for either sex. Reason being is that if you come together because you're hurt, over time, the thing that brings you together heals with time, and you become less needy. There comes a day when you realize this, and some one ends up being hurt, left hurt, and so the cycle continues in another.
It behooves you to work on yourself, by yourself, for a time, so you are a more complete person before you look too favorably at dating. If your intentions are for some "fun" dating and are made crystal clear, that's good, but understand that many women who are mature (the type you'll seriously need) simply cannot endure long term in such a relationship, no matter what they say. Without healing, you run a good chance of either finding a woman not really right for you (more like your ex), or too right for you... Meaning she'll be ahead in her own healing process and at a completely different life stage than you.
Take what I write with a grain of salt, but it has been my truth and experience. All the best.
