Contacting my ex boyfriend

Do you have any idea why you abruptly stopped talking? If he gave no indication why he stopped calling, and you really have no clue what happened, I'd suggest you move on. The truth is that someone who cannot be upfront with you about how he is feeling is not worth the time or effort you will put into the relationship because you will never have it reciprocated. Find someone who will treat you with the same respect that you will show him.

Good luck!

What kind of relationship did you have during those six months? Were each of you open enough to express positive feelings for each other? Did you allow him to feel that you were ready for a more serious and permanent relationship? If you did what was his reaction? These are questions that you have to ask yourself. If you feel that you did everything you could, I would suggest that you get on with your life and look for someone else with whom to build a new life.

6 months might not sound like a long while but its sure is enough. Contacting an ex always includes raising some hidden feelings not to talk about memories. Do you think it would do you any good? Would it do him any good. Think it over if a person would like to contact you he will find you no matter what.

It wouldn't hurt to call him as friends and just feel him out on his status, do not sound like you've been waiting on him, nor upset over being left hanging, act cool and your call is to say hi and see if he is doing ok.So you can put closure to it within yourself.  If he allowed the contact to die this long he really isn't worth having a relationship with.

MOVE ON, he's your ex. You guys are over. And you guys were together for only 6 months. You're wasting your life by waiting. Go one and meet new guys!

You'll regret talking to him.
