T you mentioned in a fairly recent post that the thing that sent your H into his crisis was loosing his own mother. Was this 'friend' that he asked to call you also there for him at that awful time in his life? If so maybe he felt this person had helped him at the time and would also be able to do the same for you.

As for this person trying to get info for H perhaps H was looking for reassurance that it was ok to be your comfort.

Just my thoughts. However if it made you uncomfortable do not take anymore of these calls if they are repeated.
