biggest regret

My biggest regret is not being their for her, and being selfish. Just recently I lost the love of my life, and now I'm just sitting here, broken, thinking of all the things I did wrong, all the things I never said or should've said. It defiantly follows the not pattern. I regret how I treated her and how I acted. She is way too good for me. I believe there is a quote some where that says you don't know what you truly have until its gone, or something like that. This relates to lies and deception, by making myself blind to how I treated her and how I took her granted. I deceived myself that everything was ok, until she walked out, now I'm just sitting here, writing this post, wishing that this wasn't the example I have, and  that I still had her.
