Welcome to the world. 99% of us are carrying some kind of fucked up baggage from the past. Human beings are just that. They're fallible and warped and pass their pain to others in fucked up ways as a means of coping with their own shit, and on and on goes the ugly cycle. At a certain point though, you have to stop it. Don't let this person's pain live inside you so that you eventually pass it on to someone else.
Time to give up the ghost.

You did the same to me

You're a really shitty person with no respect for anyone.

You claim to be a victim but you're the fucked up one.

I don't think it is 99%, it's a lot smaller. Unfortunately we have a culture where everyone is subject to abuse, and they are supposed to internalize the abuse as acceptable.

For example, many people make pledges of eternal love and companionship to teenage/college romances. Well, they should keep their words, keeping your word is more important than whether or not you are happy. They behave abusively and society sanctions it.

Rather than focusing on how "everyone has a story to tell," realize that _many_ do because _many_ others act like subhumans who can't keep their words, etc. Any animal can "do what it feels" without reason or duty or responsibility. Humans are supposed to be better.

You have to know what is too much before you know what is enough.

If you're going to dabble in love, a powerful hallucinogen, you have to be careful. Now you know.

It sucks though. The stories tell us that love is rapture, we should commit fully, we should expect the other person - one other only, a unique combination, foretold by destiny - to always be exactly what we need, when we need it, as we like it.

As adults in theory we should know this is not the truth, but until you experience it, it is hard to explain.

Good luck.
