Are you sure he hasn't seen her previous to this for dinner, lunch or anything else...could she be involved in the business some way...do you know her???
I don't know what to tell you to do...I could tell you what I would do but that might not be best for you...from the sound of that little snippet it looks like they may have not ceased contact...at least by texting...are you sure of this...are you sure that from June til now he has not been in contact with her...
Just hold tight...monitor the text messenging (although you really shouldn't have to do that...but I know you will) and just try and keep your emotions in check...
