How long to try when it was (mostly) your fault?

I think you really goofed contacting the OW again. Why wouldn't she be blocked? I hope you've done that now. And delete her # too.

You need to show consistency if you want to turn this around but you'll need patience for that to happen.

I agree with R2C on decisiveness. Your indecision is due to you wanting your W to solidify your relationship. Not gonna happen. "Be the change you wish to see".

Learn the basics around here, set out a plan, and get consistent.
