Can't decide if I should break NC

Hi all, Male, 30yrs here. Not really sure where to turn to right now, maybe its the christmas season making me feel this way, not sure. Its been almost 2 years since my ex gf broke up with me. We were together for 10 years, until one day she just didn’t feel the “spark” anymore. I want to say I’ve healed a good amount, not as much as I’d want to after this much time, 2 years is a lot of time to still even entertain thoughts of your ex, I know.

Lately, the urge to break no contact has been pretty strong again, and I’m really not entirely sure i should. I would love to have her back in my life, and hopefully be together again, but after all this time, that can’t really be possible anymore right? I haven’t been with anyone since the breakup, from a combination of no luck with women, but also not really wanting to, but I doubt things are the same for her. Her most likely dating/sleeping with other men in the time between isn’t a deal breaker, but it makes me wonder if the whole reason she hasn’t even tried to reach out either is that she’s found someone better or someone she’s happier with.

So I just kind of wonder if there’s even a point. After all this time, would i really even have a chance? Or would i just be delaying my healing more. Is it worth reopening that wound? If not, how do I fully move on? Maybe its because of how long the relationship was, but I seem to be unable to fully commit to letting go. I’m also worried she’s probably completely moved on by now.
