No more denial, time to get to work

[Twofeet]

I know if she wants to try she'll let me know.....

There is your answer.

but I'm really not sure of that with her personality. She's always been very stubborn, especially when it comes to feelings.

Do you seriously want to be with someone who is so stubborn she would rather D than work it out because of what? Feelings? That doesn't sound like it would be a very functioning R going forward.

I'm leaning towards just letting it go, but there's a part of me that wants to reach out. Talk me out of it folks!

You have answered your own questions in the first two quotes. Let it go, don't pursue, if she really wants to work it out you know she will climb a mountain to do so.
