My friend suspects her husband may be having a gay affair. She found messages on his mobile along with a video that would indicate he is seeing another man. She has given me some numbers she took off his mobile phone bill so that I can ring them and see who answers (she thinks they might be gay chat lines or something). Is there a way I can trace mobile numbers on the internet without having to ring? I really don't know what to advise her - she just doesn't trust him now and who can blame her? They have 2 young children and he works ridiculously long hours including weekends - although she now wonders if he really is working all the time. She has confronted him but he says he isn't seeing anyone. Anyone faced this before?
