I meant it figuratively when I said "following her around." I suppose I just want you to stop letting her call all the shots, and stop answering to her. You are a grown-@ss man, and you do not need to tip-toe around and explain any of your actions anymore to her. In fact, you should be saying very little to her about anything right now. Just short, yes, no answers to any questions she might ask.
Stop texting her about where you are and what you're doing. Be mysterious, but not in a fake way. Go out with friends, or just alone, and don't explain yourself to her. Period! Your life, since she claims to want no part of it now, is no longer any of her business.
You made a big mistake a long time ago, and you are obviously genuinely remorseful about it.
But that doesn't mean that she gets to keep tormenting you over it. She obviously gets some sort of sick payoff from browbeating you about it. Do not apologize to her about this tired-@ss issue anymore. Not one more time! Do not give her the luxury of her sick-@ss payoff ever again. Enough already!
I'll tell you something, if I were so bugged about something that my H did, couldn't get past it, yadda...yadda....I would pack my sh!t and get out! So that is exactly what she should do if she is too immature and spiteful to forgive you.
