My "ex" ( we lived together for ten years) has a gambling problem. It's was one of those things that you didn't notice it until you noticed it. I knew she like to play the lottery, and liked the race track. I began to notice the lies. She said she was late getting home from work because she had to buy cat treats, but then, next day, she had to stop, and buy cat treats. I found out she took the day off from work to go to A. C. to gamble, without telling me about it. There was just so many more lies. I went to Gamblers Anonymous. I asked if she had a problem. They told me that I knew she did, and I did. They said the since we weren't married, as soon as she found out I knew about the addiction, she'd be gone. I don't know what it was that told her I knew, but she left. I didn't try to stop her. It wasn't the gambling. but the lies. I wasn't that sad it was over. Haven't seen her since.
Afterwards, I found out she was spending a minimum $10-20 daily on lottery tickets. (At least $4,500- $8,000+ on lottery tickets alone.) Plus she lost many more thousands at OTB. I don't know how she did it. We made the same salary, and I couldn't afford that.
