Dear Steve and Shirley, I’ve been with my girlfriend for close to a year and she has a problem with talking behind my back. I noticed a change in how her friends greeted me and acted around me but I didn’t think much of it, until I found out why they were doing that. One night my girl got an attitude with me because I was playing a video game and she wanted to argue about it. She started texting somebody back-to-back and when she fell asleep, her phone was still dinging.............
