first off, once caught, lay low for a while & never repeat the behavior which got you caught. Seeing a provider is WAY different that an affair... affairs are emotional & have strings... and are on going... seeing providers is NSA. No strings Attached.
Do not change your schedule. Over time try to loosen up your schedule a little bit. Lots of guys only hobby when they or wife is out of town.
Once a month is quite doable... no patterns... random. I like the midday to early afternoon time which fits my schedule.
Never involve others as a cover... too easy to get tripped up... and risks an ex-buddy getting drunk or pissed off... need I say more. Activities, workouts, gym, golf... must make sense for YOU. You might want to develop a hobby or interest she doesn't share but which takes you out of the house some. Even going for walks in different locations like parks further from home... for exercise... but the catch is you must really do it MOST of the time.
Building model planes would work too if you have to go to hobby shops & hang out with radio control freaks...
Take up wood working... with many visits to home stores...
Just get out of the house. Have other things to do than go straight home!
I increased my spending money from each check by a small amount... which I accumulate in cash (no ATM trips to link to my absences). I refill my wallet daily from my sock drawer... but my play money is well hidden somewhere else. Any excess in my sock drawer become play money with the next check & is moved.
Don't use your personal cell. Ask Tiger!! Get a Hobby Phone. Turn it off when not in use. Hide it very well.
Don't access adult sites from work or using company equipment (unless you own the company & can withstand the heat when discovered.). Don't use shared home computer with others in the house. Set to delete browsing history on closing or use another browser on a thumb drive. NEVER turn over a running computer... Oppps, accidentally shut it down. Use an over write program like CC cleaner often.
Don't use your regular email... or an account linked to it.
Wash face, hands, privates before going home... women can sense sex smell even if they don't realize it. Use the same soap. (Some guys shower at gal's place or gym) Don't go straight home... wait for the high to pass before going home.
In short Don't Leave Tracks... If you want to enjoy long term... you must keep under control.
