<human>: About a half year ago, I tried a LDR with someone I had very strong feelings for, but it ended pretty badly. We only went on one real date before I left for my internship and did an LDR for a month. If I guess why we truly broke up from my point of view it will look like I'm blaming her for something I'm not sure on so I'd rather not. Anyways, she said maybe when I return to town we could try being in love the right way. A month after she said that and we did no contact she started dating someone else in an LDR, so I was pretty crushed. I did my best to convince myself this is a better choice for her, that she's happy now and that it wasn't meant to be.

But it's been a half of a year since then and I don't feel better. I've gone to therapy but it felt like putting a band-aid on a gunshot wound. I've done all the things people suggest, including hobbies, friends, family, time alone, dating other people. And still whenever I do those things I keep thinking about her. I've taken her off social media, but I keep seeing things that remind me of her. Whenever I'm with friends or doing a hobby, she keeps fading in and out of my head. Whenever I go on a date I always find incompatibility, and when I'm alone after I just daydream about her. It doesn't help that I'm back in town and I saw her on campus today.

People keep telling me "you'll meet the right one." I'm sure there's other great people out there, but nothing is guaranteed in this life. I don't know if I'll ever be able to get this girl out of my thoughts, until I find someone who I like just as much, if I ever do. How do I cope with knowing that I screwed up something I wanted more than anything, and knowing that no matter how badly I want to, I can never see her again?

<bot>: Relationship ended badly, it's been a period of time and it still sucks just as much as it did when it happened. How do I cope with this seemingly permanent emotional baggage?
