You ever loved someone so much

Have you ever loved someone so much that it hurts and it doesn’t matter what they do you will always love them ?

I still love my ex and even though he’s with someone else I still love him and want him back ?

Why I don’t know he’s never really shown much affection towards me he’s quite a closed off person.

Even with being closed off and being with someone else I can’t picture him not in my life, in a weird way he makes me feel happy and safe.

And the fact that are family’s are best friends doesn’t help either I see him most of the time.

I just feel really hurt and upset and don’t know why I still love him or want to still be with him, if he turned around and said can we try again I would in a heart beat.

Is this normal that I can’t see myself ever being happy again with out him ?
