Hey grasshopper

dont beat yourself up about - we all have days and times when we slip into 'old' ways and cant help ourselves from saying something...

The best thing now is to completely forget about it. Dont mention it again to your W. Just act as though nothing happended and go back to doing what you did before...

I dont think there is any harm now and again to say what you think anyway - as long as its not every week. now and again sometimes can have a good effect and make our partners sit back and think...

Think you also need to accept in your own mind that you W might have been meeting a friend, who knows!!
But by getting jealous and questioning her is not going to work, unfortunately this could well push your W the other way...
Try and ignore it.......
Better still - you go out shopping one day and do the same if she tries to ring you... create a bit of mystery about yourself... make your W start worrying about where you are and what you are doing for a change...

good luck
