Cathy had a feeling her husband Jack was having an affair with his boss, June. But each time she asked, he denied it. June was "just a friend."

"When you spend all your time with someone and have no time for your family, something's going on."

It was the night of their son's 20th birthday. Cathy was driving home from work. She was going to make all his favorite foods for dinner. As she past a bar, she noticed June's car in front.

"I stopped in, just to see, and there they were. I had a beer with them, and we talked about the dinner we were going to have. As I sat there, they would occasionally converse quietly and not include me in the conversation. I said to my husband: 'You're making me uncomfortable. I feel like I'm the third wheel.' He told me I was imagining things."

Cathy left to start dinner. Jack said he'd be home at 7. At 8, she and her sons ate dinner. "He showed up at 9, drunk as a skunk. He jumped on me, yelling, slamming doors, screaming, telling me he wanted a divorce.'"

Jack said he was leaving. "I said: 'Stay home. You're in no condition to drive. Sleep it off.' He went upstairs. I ordered a pizza for him. When the pizza came, I went upstairs to see if he wanted to eat. He had snuck out of the house down the back staircase."

Cathy went to June's house. The door was open, and she went in. "I slugged him three times. He raised his fist to me. I said: 'Go ahead! Do it, you sorry piece of crap!' All the while, June was falling over because she was drunk. I told them they deserved each other and left. I went home, packed up everything he owned and threw it out the window. It landed on top of the garage."

This happened 17 months ago. Cathy says Jack still hasn't apologized to his children for breaking up their home. "I don't expect an apology for myself. He'd had an affair once before with my so-called best friend. I made him tell the kids what he did. Back then, he said he was very sorry. He didn't want to lose his family. This time, he showed he didn't care."

Jack is now living with June — or, as Cathy calls her, "the idiot."

Cathy had to move out of the home she, Jack and their 15-year-old shared. She's now in a "dump of an apartment." She had to sell her car and buy a beater. "We also had to go on food stamps."

Jack, meanwhile, is enjoying the high life. "They have a big-screen TV, new dining room furniture, a pool table. Everything he gets he posts on Instagram."

Cathy would love to divorce Jack and be through with him, but she can't because she needs his health insurance. She has two preexisting conditions, diabetes and diverticulitis. She's priced insurance and can't afford it. The deductibles are so high that she'd never be able to see a doctor.

"The funny thing is when we were married, we always had great sex. Go figure."
