First off its creepy. You know her workout routine by the day of the week and comment to her about it. You see her talking to anyone, especially males and immediately go ask her who it was. Dude, she is married! You are older than her by about 20 yrs.

And don't walk up to her if you see her outside the gym and tell her she cleans up well. Especially don't do this while wearing BYU gear. You look like an idiot.

Tldr, don't hit on married women and be a creep.
TIA
