have you ever been in a relationship where, although you've been together for some time now, you can't quite shake the feeling that something just isn't right? you seem to be putting in all the time & effort, and your other half just isn't pulling their weight. and although you try to keep going, there finally comes a point where you have to admit it - this just isn't working.
sure, you can try to ignore the obvious. you can try to distract yourself with other things.
but eventually, you just have to come clean - you just don't fit. you're at a stage in your life where you really just want some time on your own. you need to spend more time on your career. you just don't feel like you have anything left to give.
it's not you - it's me.....
