Waiting and hoping and having no clue

So, I wrote my ex-girlfriend a letter. I have finally gotten to the point where I am comfortable enough to be friends again. Our last fight is what ended our relationship and we just stopped communicating with one another. I have found out that she wants her old boyfriend and I am okay with that (not all that happy, but I am finally okay with it). So, since we haven't been communicating and I had lost a small thing of hers, I replaced it and gave that and the letter to her mom. At the end of the letter (which I photocopied so that I can actually include it in my book), I told her that if she didn't want anything to do with me, I would leave her alone and that she needed to contact me in order for us to have a friendship again. I didn't want her to feel forced to communicate with me, so I wasn't all that comfortable staying around her and stuff. I'm just hoping that we can be some type of friends again. She's the one that I gave my virginity to (yes, I was thirty before I was willing to give it away, that's a story for another day), and I do actually care about her, but I don't know how well she took the letter or if she even read it or gives to shits about me. It's something that I'm going to have to eventually be okay with, cause there is a decent chance that she doesn't care and I'll never hear from her again. So, tonight, I'm accomplishing a few projects and now I intend to watch a movie and probably drink half a bottle of wine.
