the affair that broke my marriage

ive been married for two years now and everything was going well until... a coworker at work, she's in hr actually. i started seeing her every chance i got over the last few months, meetings, lunch breaks, any excuse really. it started with small talks, grew into lunches together, then eventually to places no one would see us. we're both grown adults but... its hard ignoring what ive been missing from my marriage and now here i am. im not proud of myself but i cant stop thinking about her either. anyone else ever cheat on their spouse?
