I have found out (unintentionally and was not snooping) that my partner and his ex (they have no children nor mutual friends together) have been exchanging messages initiated always by her but he responds pleasantly.
The last message however was her saying she is always ready for him (in a sexual tone) with him responding "no you're not but you should be".
How would you feel about this? We have been together for a year (we have no children and are not married). Should I take this as just tongue and cheek on his behalf or should I be concerned?
Part of me feels it was a playful brush off, I mean what else could he have said?
I have mind fog at the moment. Please help me see this from an outside perspective.
