What you're really saying here is:
"I like it the way it is, don't bother me when I'm exploring this realm."
Bingo, hit the nail on the head here.
You have a lot of people here telling you this girl is trouble, and it's not out of a need to keep you single or anything. You've asked for advice, received a unified response from many members here and are ignoring it because she apologized.
If dumping her will make things go back to the way it was then I'm all for it. But I want to have confidence going in the doing so will likely produce that outcome. Since I already tried to move on from it, told her I forgave her, and talked about it, it makes me concerned that dumping her will cause her to question me and not want to be with me.
Dump her because you don't want to be with her, not as a manipulative tactic to get her to behave the way you want.
Hearing your guys input remotivates me to get serious about inner work and not just using it to hold onto the relationship and do the minimum.
That's exactly what you're doing here though. True inner work begins when you're willing to prioritize honesty over having things stay the same. Honestly going inside and looking at what's there might make you realize that the relationship was or has become a farce. It might not, but you have to be willing to explore that and accept it as a possibility.
Because choosing who you want to be with is the goal of all this, and you can only be as selective as much as you value your self. And you will never be happy in a marriage or long-term relationship if you're in it out of fear and not love. Or if you act mainly out of fear and not love. You're painting this picture of the situation where it seems you need the girl to feel complete. It's a recipe for disaster, as can be witnessed throughout these forums.
Obviously, it's your call though, so as Kidd said, godspeed.
