They come and go, like the seasons. Right now for me, it's gone and moved on. Not that I'm complaining but it's different.
I was in a relationship that seemed to be going toward something bigger but... The timing wasn't right and neither were the conditions. We wanted the same end goal but our paths there really didn't align. I have a lot of plans I want to accomplish before I settle down. While it felt she wanted to grow up too soon. (I'll spare the details)
Although, depending on someone for so long then having no one but yourself is, a lonely experience. Like realizing your best friend has to move away. It's not what you expected or wanted but something you have to deal with.
What I think the hardest part is breaking the habits. You know, sending texts with the heart emote, telling your SO that you'll see them tonight, or something as simple as wondering what they are doing. Leaving those behind is an exercise in emotional tempering. It's one of those things that get easier over time I suppose.
On the bright side, I remember being single (after a previous break up years ago) and feeling the desperation of finding someone to be with but, this time around, I don't think that's the case. I feel like I'll enjoy my new found freedom. Shit, I might find myself some trouble. (Like I know how)
