I've made a post before on how communication is key and thought I'd like to add on to that. My breakup is still barely a month fresh and through lots of thoughts and self reflection another thing I've realized for the sake of those out there.
A mistake I realized I made was focusing too much on the future that I neglected the present, taking a lot of things granted. I put on a lot of unnecessary stress on myself by worrying about marriage, the house , basically things that were beyond my control as I am still an undergraduate in my bachelors degree.

There were signs of neglect and being too comfortable on my end and my partner needing me to be present but my sights were too far ahead on the future I wanted to give her. It's okay to talk and plan for the future but do not neglect what you have now. There will always be work to be done. Do not take time for granted.
