Relationship being described as stable

[thisisgettingridiculousagain]

Have been happily with DP for over 5 years now.

Overheard him when asked if he was happy with our relationship, he responded 'it's more stable'.

I feel a bit

My sister thinks I am over reacting, but I feel a bit sad. Not sure why I posted this, but looking for reassurance I guess.

Just how they worded it - are you happier with the relationship now? It's more stable. It sounds a bit like a therapist asking, if that makes sense? It's certainly something I wouldn't dream of asking an acquaintance.

My sisters assessment of the situation was that she is quite the brazen type and felt nothing of being so direct and asking him about his relationship. In his awkwardness at being asked, he came out with the stable comment.
Nothing untoward, and I should move on.

My issue is that brazen or not, he told her something years ago that implied we were going through a rough patch. She would still have been an acquaintance then, yet he chose to share such personal information. I can just about accept that, maybe he made a mistake being so loose with information.

What I can't accept is that, to put everything to bed and move on from the episode, he should have responded YES I AM HAPPIER, when asked this time round. That would have killed the conversation. By saying stable, I can't help but feel that it opened up room to discuss further. It wasn't an answer to a question, it was something a politician would say .

Now that I have written this out, I think i've convinced myself to ask DP about it. It may seem quite small, could be clumsy wording, but it is getting to me.
