My wife and I been married for 13 years, we have a 6, 9 and 11 year old. Recently my wife been hanging out with some new friends that I don’t like and been neglecting me and the kids. She’s now partying every weekend when she used to barley go out. She has texts coming to her phone weird hours of the night and now she locks her phone when she never used to do that. We both had each others codes to the phone and now she changed hers. She dresses real provocative now and spends little to no time with me. Do you think she’s cheating on me?
