It starts out ok, but there is a definite fine line that is easilly crossed. Take my experience, tell me where the line was crossed.
1) Had a wife (11 years together, 6 married).
2) She works evenings as a ballroom dance instructor.
3) She dances with all sorts of men all day long (dancing means thigh/thigh and/or chest/chest contact). Of course, I dance with all sorts of women, so this isn't an issue.
4) She starts hanging out with the other dance instructors after work on Tuesdays (usually to a bar).
5) She later starts hanging out with just two dance instructors (one of each gender) on Thursday evening (usually to an apartment) in addition to Tuesday.
6) She later starts hanging out with one male instructor M, W, F, Sat, and Sun in addition to the Tuesday and Thursday outings. They go places and do things she has always refused to ever do with me (innocent things such as drink at a bar, play pool, go bowling, watch a movie, etc).
7) She quits and opens a dance studio with one male instructor. They work all day together, eat lunch together, do "business planning" after work together late into the night.
8) I snoop her emails and they are all love emails discussing intimate body parts and corsets.
9) I file for divorce.
10) I find a loyal GF and am much happier now.
Where exactly is that line crossed? I had a ton of trust for my wife and got burned. I say the line was crossed right around point #5. Others may say it is crossed a bit earlier or a bit later. Either way, jtvang125's description is right near my point #5. Has that line already been crossed? Are they already at point #6 or beyond and he doesn't know it yet?
The Dear Anne newspaper columist said it best: (paraphrased) "if it is work related and necessary, there is nothing wrong with it. If it isn't necessary or work related it probably is innocent but the chance of raising problems is too great to risk. Avoid it at all costs."
I bet all these lunches are not necessary, and thus they have crossed the line. The fact that people are talking about it behind their back is proof enough that it is causing damage (emotional/trust damage to the spouse that is left out).
