I confronted my boyfriend about messages on his phone and finally about a week later he finally came clean and told me he was answering personal ads online. He claims he always stopped before meeting up with any female. And he answered the ad "with no intention to follow through." He also couldn't give me a reason why he was doing it either. Today is our 3 year anniversary. I'm not to sure if I should believe him or run as fast as I can.. HELP?
