what the...hell?

I had hoped that it would only be temporary, hoped for a month or so.
I gave up after that month or so, sure that we were done...
But now he says he wants me back and I dont know if I can trust him anymore.
After everything that have been said and left unsaid, how can things go back to the way they used to be?
Should I give it another chance or am I just setting myself up for another fall?
I dont know if I should be opening my "not so old" wounds, but what if this is a good thing?
This could really go either way: bizarrely right or horribly wrong.
If I choose him I have to give up my other options, which normally wouldnt be so bad but after everything thats happened, I kinda like having options.
I dont want to hurt anyone of them, but I dont want to be hurt either...
I know I'd have to choose someone at some point...
I just don't want to make the wrong choice...
I know I have a tendency to over think things... well Everything.
My dad says not to worry so much, but I dont see how thats possible... It consumes my thinking
how can I possibly focus on other things while this which has been lurking in the back of my mind surfaces and smacks me in the face?
Giving me pathetic reasons and excuses is useless. I cannot trust words, for words really have no meaning. Multiple meanings make those words counterproductive and in the end worthless.
Say what you feel needs to be said, but I cannot take them at face value; you saw to that.
I cannot look back, especially on the times when I was truely happy with the way we were, without second-guessing everything.
Do you see what comes of being intentionally devisive? Alls well until you get caught. Now you repent. Now you regret. But I still cant fully trust your words.
Give me more than words.
Show me.
