My wife and I had an argument July 4th and she decided she didn't want to be around me. She didn't go with me and the kids to watch fireworks. She says she went to her parents apartment who were out of town to drink. She ingored me and didn't return home until 3:30am. I feel like she was with another man. She has admitted to meeting a man at the apartment playground for our daughter and his daughters to play and after reviewing phone records for the last 3 months I see they have texted each other over 300 times and she has called him about 12 times speaking no longer than 8 minutes. She says there was no affair. I am 98% sure there was. How can I forgive her?
