Should i try to get my ex back if he is willing to change?

He knows where you are, knows how to reach you, but so far hasn't put forth an effort to even find out the reason you broke it off! In all honesty, I'd say IF he did care or wanted to get back with you, he's sure had the time to give you to show he's now interested again. To me, he's just NOT putting forth any effort in my way of thinking that would lead you to believe he wants to get back together. I would just leave things as they are,keep going forward with your life if he does want you back, he sure could easily find you, Again I'll use my own famous words I've used for yrs. that have proved to work well for me, "when in doubt, don't". Of course you can do as you wish, but if I question something, I hesitate to do anything about it...best to you...:)
