With the exception of you no longer saying "I love you," your story freakishly mirrors mine. It's been nearly three years since our relationship ended, and I've gained a ton of insight that I hope can help you expedite your healing faster than mine.
For the longest time, my attempts at moving on felt completely in vain. I was pretty successful with online dating, and had the pleasure of meeting some incredible women, but I couldn't get past the misguided guilt. So much so, that it almost felt as though my ex was sitting right there with me and my dates. What's more, I spent much of my thought-life comparing and contrasting everyone with my ex, and even daydreamed of reconciliations. It was brutal.
As time went on, I eventually came to form two very helpful perspectives after growing so sad and frustrated about what I lost.
The first of which was when I started re-purposing the way I viewed that chapter of my life. I couldn't exactly pull an Eternal Sunshine of the Spotless Mind and erase every memory and every moment from my brain, but what I could do is look back on that relationship with a sense of gratitude. Although it didn't work out for us, I still learned a great deal of helpful things about myself, women, love, and growth. Those lessons vary depending on the person, of course; but in doing so, that chapter of my life felt less haunting and more valuable to me as a living, learning human being. And eventually, that kept me from repressing or running from my pain.
The second, and arguably most valuable perspective I gained was realizing that I had essentially created a fictitious version of my ex in my head. That version of her was the one that existed back when everything was amazing with us, while the real version of her was the one that checked out and never wanted back in again.
Realizing that helped me see that the person I couldn't get over, the person I missed... well, she didn't exist. She wasn't real. Better yet, I also realized that I actually didn't miss the real version of her at all -- the one that grew cold and abandoned me. I know that the real version of my ex is still a good person at heart, so that wasn't me trying to vilify her like so many other people force themselves to do to get over someone. Far from it. I was simply coming to terms with the fact that the woman I knew and loved was gone.
Thus, I had to essentially break up with the fictitious "perfect" version of my ex. I couldn't love, much less miss someone that wasn't real. And I damn sure couldn't let her undermine my future by taking residence in my heart when I really needed to clear that space for someone better down the line.
To some people, that will all sound like a bunch of crazy talk, and I get that. But I think there's a lot of people out there that will know exactly where I'm coming from.
Point being, you'll never reach a point in life where you'll never think about her. But, don't let that frustrate or discourage you. You see, it's not about how often you think about your ex that counts. It's what you think of when you do think of her that matters most. So, with those two perspectives in mind, I'm able to think about her as an important era of my life that taught me a lot, but belongs in the past because she isn't what I long for anymore. She used to be, but not anymore. Now, I'm able to move on and enjoy my dating life without that obstruction blocking my happiness.
Hope this helps.
