Soul Quake is right. I have personally been through this, and made excuses for the sorry fool. "oh he's busy. His work is everything. Blah blah".

But I knew in my heart I was justifying him ignoring me. We were together on Thanksgiving, and then he disappeared. Poof. I finally wrote him a letter before Christmas saying that I wouldn't put up with the silent treatment, and I didn't hear from him.

It's funny how we make others problems ours, right? And even justify them not wanting to really be with us by making excuses.

But if he's always busy, then he's too damn busy for you. As someone who has learned the incredibly heart-breaking hard way, it means it's over. Let him go and move on.

There is a great quote from Mad Men that resonates with me when I see things like this.
"men don't take the time to end things. They ignore you until you insist on a declaration of hate."

And sadly, it's true.

I wish you the best. Because you deserve better.
