NTX, don't beat YOURSELF up over mistakes you've made in the past or recently. You can't time travel. You can forgive yourself and act differently in the future. Don't buy into the blame game, the "you had a chance and it's now gone" script.
Admit your fault where there was one, apologize sincerely, validate your W's hurt and make an amend as appropriate, and then move forward for yourself.
Like others have said, it is easy to feel like you are walking on eggshells around your WAS. That any wrong move will be the dealbreaker, the straw that drives them away for good, the one missed opportunity. Sometimes they will say that to you. (THAT'S IT, I KNEW YOU HADN'T REALLY CHANGED!). In the moment, it seems so real, that you lost your window of opportunity, that you blew it.
It's not true. Perhaps they say that to justify their continued waywardness, perhaps they really were softening and it is how they feel in that moment of hurt. Who knows, don't try to mindread it.
Instead, focus on yourself and your choices. Keep living your life, being the best (imperfect) guy you can be. If the window back is there, she will open it, and the occasional eff up on your part will not deter her.
