"Actions speak louder than words" Texts are nothing but words. Women in particular spend a lot of time "trying to figure out" what men want as if there is a "secret code" or hidden meaning. Keep the following in mind.
1. It's not about him. It's about you. Is he saying and more importantly doing the things you want in mate. If not move on. You are far better off dating someone who (already is) what you want instead of hoping the one you are with will one day become what you want.
2. An ex is an ex for a reason and it's usually a good one!
It's not uncommon for an ex to try and stay in contact to see if the ex still has feelings for him or her. Very rarely does getting back together lead to a "happy ever after ending". Most of the time it just leads to being in a "booty call" or "friends with benefits" relationship. They're just passing the time with someone they are comfortable with until "the right one" comes along.
It also keeps you from moving on emotionally and putting yourself in a mindset (to give and recieve love) from a potential mate.
3. Love is NOT complex.
When someone loves you and wants you there is no mistaking their intentions. They don't play any games. A text is a cowardly "one way conversation". If your ex is not picking up the phone to call you or coming by to see you then he is waiting for you to make the "big move"
4. Clarity/Closure are both overrated!
When a relationship is over it's over.
If you ended it you know why you did.
If they ended it knowing why will not help you feel better about having your heart broken. Whatever you did that was not "right" for him could be the same thing that causes another man to fall madly in love with you!!!
It makes no sense trying to be perfect your ex. He's the past.
5. Always be YOURSELF. Ultimately we're all looking for someone who will love and adore us for who we are.
It's time you took down your rear view mirror. Your future lies ahead of you and not behind you!
Best of luck!
