Tears dry on their own.

We meet so many people along the way, some we think we are going to know forever and some you realise from the on-set that you're not gonna know them for very long.  With others you can misjudge the depth of your relationship and you could end being closer to them than you thought.  But generally I think with romantic relationships most of us don't generally assume the worst. You hope for the best, wonder if they are the one you're gonna be with forever, if you believe in that sorta thing.  So when things don't turn out as planned or hoped you can feel so cheated of the time you feel you wasted on that person and you count all the sacrifices you made and you resent them.
Breakups are generally always bad, someone always walks away from a breakup feeling disgruntled.  Some breakups can be exceptionally bad and it can take a while to put the proverbial pieces back together. Some people can obviously bounce right back and move on while for others it can be a more lengthy process that involves a lot of resentment and unhappiness. They still feel wronged by that person and have a hard time letting it go.

There is no formula to "get over it". We all have our own way of dealing with things but I think more than anything you need to forgive.

A few years ago I ended a relationship on not so very good terms. I was angry, I was hurt and I really thought I hated this guy. I continued to feel like this for a very long time. He tried on numerous occasions to make peace with me but I rejected him over and over again because even the thought of breathing the same air as him vexed me beyond words. The thought of him made my insides boil...well you get the picture. And I really thought I would feel like this forever. But the truth is, I didn't.  I don't know if it happened overnight or if it was a gradual buildup somewhere in my heart or psyche that just told me to forgive him.

I can honestly say that it took me like three years to get to this point, and, there was something so liberating about this forgiveness that made me smile. That made my heart smile. That I no longer wished he would get hit by a bus, multiple times Lol
He reminded me a few times how we were once friends & he didn't believe that we couldn't at least get back to that.  Although this idea seemed laughable at the time, after I forgave him I was able to see him as a human being again that makes mistakes like I do.  And more than anything, there is something so liberating about not living in the past. You give your heart more room to give other people more love once the shackles of that hate and resentment are lifted.

Forgiveness is a truly beautiful thing. You should consider it.
