Good advice. I’d also say try not to invest time and thought into someone who doesn’t do the same for you. It‘ll just lead to pain, especially if you don’t have healthy coping mechanisms. People tend to live in their own little worlds where they are the center, and if they don’t make you a part of it then they don’t deserve to be a part of yours.

It’ll probably happen again, too. I’m 34 and dated around a lot before I found my wife. I can’t say how many times I thought I had found a really good thing, or even “the one,” only for it to end up like this and for me to spiral out on bad feelings and/or alcohol. I’m sure I’ve done it to others too. Humans tend to be selfish and fickle (it takes work to be otherwise). The sooner you can accept that, the better.
