TITLE: I'm [25M] curious about my partners [31 F] relationship history
POST: I have been dating Charlotte for almost four months. We are exclusive.

In the past, I have had no issues or desire in discussing exes with any previous partners. I expect people to have history, as it is natural.

Charlotte has always been tight-lipped regarding her previous relationship, but recently revealed that we met a few weeks after her childhood sweetheart broke up with her after 12+ years. They also own a house together, which she has remained in.

I do not know anymore details other than the above. I feel like asking direct questions would be disrespectful.

I have not dated anyone in the past with a complicated history, and my gut tells me she isn't over the break-up (which is understandable).

Basically, I'm wondering whether it's worthwhile pursuing. I do not want to be seen as the person to fill a void. Can anyone offer me any advice on how to proceed?
TL;DR: 
Partner met me only a few weeks after a messy break-up. The fact they own property together and my instinct that she isn't yet over the LTR makes me feel uncomfortable.
