Another source added, "He was always kissing other girls. When you're a bachelor for 50 years, it's hard to break old habits. But she loved him and wanted to make it work. He loved her too, but had a hard time staying focused."
Viewers of the Real Housewives of New York City watched as Luann was confronted by her co-stars with allegations of Tom cheating and making out with other girls. Many even voiced their concerns about a possible wedding. Instead of listening, she would keep them far away from her New Year's Eve ceremony.
As to why Luann decided to file today, it appears the Bravo star simply had enough with all the reports and rumors surrounding her marriage.
"She just broke down and got tired of trying and hearing these stories about his infidelity," a source shared. "She's going away tomorrow with her kids to regroup. She's a mess."
