Moving on... it is a funny concept isn't it? You pour yourself into a relationship just to see where it can take you. Sometimes all that you receive is the opportunity to see that when you were done pouring there was absolutely nothing left. You are totally drained. Then you refill, never being totally full again, and you move on. Moving on is easy, it is suppressing the what ifs and the memories that is hard.
Personally, I think it is healthy to think about exes every once in a while. It doesn't mean you aren't over it; it just means that it mattered to you. I'd be lying if I said TimeHop didn't ever pull at my heart strings, but to each and every picture that reminds me of a past relationship I can honestly say that I smile, remember the good times reflected in the photograph, and again I do that funny thing... I move on.
I refuse to believe in the ridiculous theory that one day you can just be "totally over it." Yes, obviously you have the ability to one day no longer have feelings for someone, romantic feelings come and go, but I don't believe in the idea that one day they just stop meaning anything to you. You cannot go back and erase time. You poured everything into them and though you gained majority of that back, they will always have that small piece of you that you cannot quite fill in again.
I think that small piece has something to do with the fact that no two people are exactly alike. Nor are any two relationships/experiences. Some may argue "I have a very specific type" but frankly that doesn't matter. As cliché as this sounds, we are all snowflakes, no two the same. I think in the slight differences we find the portions of our heart that we aren't able to refill. People's differences set them apart to hold a separate place in our hearts.
Thank you for enduring yet another rant by yours truly. It is always a pleasure making your acquaintance.
