She's asking if there's a chance to put the family back together.
What are your thoughts on this? She seems to temp check you fairly regularly, do you think this just another temp check or does it seem different? Where are you on possible recon after all she's put you through?
Agree with Steve's response, if you're intending to respond at all.
EDIT- the fact that she texted this makes it seem a little contrived. I think I would just not reply at all, if it's really that important to her she can tell you in person and then you can hit her with Steve's suggestion.
