If he has even started feeding you the Bullshit that he is feeding you here in your OP then you really need to walk away and not except his crumbs!!!
You got all tied up in him and he didn't feel the same, yes he probably fucked you and told you sweet nothings but guys do that...sleeping with a woman doesn't mean what it means to a woman...you catch feelings, he only feels with his dick.
Walk away and don;t look back...you are only going to appear desperate and more unappealing to him!
It's not just that...you will still mourn the relationship. You just have to realise you won;t get the answers you want that you think will help you move on...and in my experience, it's probably better to NOT know the truth.
The truth cuts more than you know and it's better if you can deal without knowing it all.
Remember the saying "curiosity killed the cat" 9 times out of 10 this is true!!!
No, she thought it was other woman throughout their marriage...once she realised it was men she wished him on his way and moved on with her life so easily. I was stunned!!! Now I understand. I guess you have to be in that position to understand it!
He lives his life still a secret, they have 3 beautiful children that will never know the truth...or at least he will hide it from them for as long as possible. Imagine living your complete life a lie...it's really it's own bit of karma don't you think???
The expectations are yours, what you think he should feel because that is how you would feel in the same situation.
In my experience and with my Libra ex, he walked away never to look back or feel sorry or anything...and that was the hardest thing to take, the complete ignorance of me and my feelings.
BUT in the end you have to deal with YOUR issues and learn to move on from it. You won't get answers or see him get his karma, you won't experience any glory. The longer you wait around for answers or understanding the longer it will take you to be able to move on.
Sometimes, it really is a case of not meant to be and most of the time it is for the better.
I hope you can find the strength to move on and quickly without your feelings being acknowledge by him...
A Libra will only waver if they weren't totally sure themselves that they wanted to end it. If however, they were definite then there's no going back, not permanently anyway.
And yes they will feed you full of shit when you call them out on truths that make them look like cunts, remember they don't like to look bad or be wrong. They will then go behind your back and turn it on you so that everyone that you may be in contact with from the relationship will think that you were at fault and the pyscho ex. You contact him and that will be more ammunition that he will use to prove his theory.
As hard as it is, keep walking and don't look back. You know in yourself what he has missed out on, even if he never does see or feel it!
