My Marriage

[MrD]

I just had a weird dream, I dreamt that I found out that S7 is not mine.
Then I started thinking maybe that's my W's dirty little secret.
I started piecing things together, at the time S7 was conceived I was traveling very heavily and the W was working alot of hours in her new position at work.

A couple of weeks ago during one our recent arguments W mentioned briefly that our sex lives at that time S7 was conceived that she was surprised why I didn't doubt that S7 was mine.
And I've noticed that lately she has really treated S7 and S12 differently.
This right now is bothering me.

Is there a way to find out?
