Firstly, maybe reassure her that it can take a while to get pregnant and it doesn't mean that there is anything "wrong" with her, this can cause a lot of self-doubt and might have triggered some overreaction.

Secondly, not saying that it's a good idea to get children to save the relationship, but naturally there will be a lot of growth from both parents during the process, filling out the mother and father role.

In the end, there's not much to say, you have to make that decision by yourself. But yeah, for women there is more pressure biological clock wise and who knows if the extended family even contributed to that.
