Why am I still hung up on this one person?

The reason I was so hung up on one person was because after years of terrible relationships, I had a few blissful days with someone who was a genuinely caring person. However, my own insecurities ruined that relationship, and my regret kept me thinking about it for a long time.

You are hung up on this person because you have hope. Whatever they might've done to you, you still think highly of them and you don't want to just give up what you had with them.

Everyone, I believe, always has that one person that they can't let go off and are attached to, even if that person doesn't feel the same way, so don't worry it's perfectly normal! To answer your question, I guess it's a personal thing and there is no definite answer, but that's okay too! Maybe you have become attached to them, because you have created a deep emotional bond with them, that can be a hard thing to deal with, but some times letting go is actually less painful and you'll eventually find someone much better, and won't even think of that person anymore! Don't worry it will be hard at the start, but have faith and courage in yourself and trust, it will get easier, best wishes :)

There is no specified time to "get over" someone. There could be a lot of reasons. Do you have unresolved emotions about or with this person? Do you currently still talk to or see this person? Are you creeping their social media profiles and keeping tabs on them? Are you associated with them still in any manner? I suppose ideally we could just forgive an forget, never look back and move on completely. Honestly there is not amount of time in which to measure how much, how little or when there is a time to stop any type of emotion regardless of whether it be with someone or even about something trivial. I believe that when the time comes you will know that you're no longer "hung up" as you say and when you feel ready for whatever it is you want to be or need to be ready for then you will be "un-hung" not because you do not want to be "hung-up" but rather because you will have used your own intelligence, insight, and interpretation for you to answer your own question.

Feeling hung up on someone could mean that there's unfinished business in the relationship. Maybe things ended suddenly. Maybe you didn't get to say something to that person and you're still thinking about it. Sometimes it's possible to get closure and sometimes it's better to let things lie. If it's appropriate to talk to this person about how you're feeling, then do it! Be bold! If it's not appropriate to talk to this person about how you're feeling, consider writing a letter that explains how you feel, but don't send it. Sometimes the act of just getting your feelings out can be cathartic!

Because it hurt to know he could leave me at the drop of the hat. I never really meant anything just when I wove my world around him?

People can leave footprints on our minds and sometimes it's very hard to clean them off. They might have loved you dearly and as that's been taken away - you don't have that love there any more to a certain degree. The way they loved you if that's the case will always be with you. If it's the other way around and they didn't love you, you may be stuck seeking approval or validation from this person. No one is superior or inferior and everyone is sovereign.

There's a part of you that's not over this individual yet. There are ways to move forward: writing your feelings, venting to friends, meditating on your future love life, picking up a new hobby, meeting new people, and seeing a therapist/counselor. However, moving on from a romantic relationship, crush, unrequited love, or broken marriage is hard for everyone who's ever been in that situation. Sometimes it just takes time.

You could still be hung up on them due to still existing feelings, or missing the memories or attention. No matter which it's okay! We all have to move on and accept that life keeps going. Focus on you, not them. Love yourself. The right person will come along at the right time.

You may have fallen in love with them. It's not something you can control and it can be a beautiful thing.
