Yes. I found out after my ex of 3 years randomly decided to dump me. He even kept my valentine's day present (concert tickets) and went to the concert with his new girlfriend 3 days later, and they were saying " I love you" to each other. It made me sick because we were supposed to get married, and I believed him, and trusted him. I'm over it now, it's been over a year but looking back at 3 years of a lie gives me chills.
