I need advice on how to handle this. I am a married woman, a civil servant. One of my colleagues in the office, a married woman. This woman comes to my house to borrow money from me and other things too because she complains a lot of not having this or that. It is not up to two weeks I found out that this woman is my husband's girl friend through bank pay-in slip. I didn't know that my husband even had her number. I hid the slip, two days later I checked my husband's phone, come and see love messages on Whatsapp. I did not behave as if anything happened because I don't want quarrel. As she has been scattering my marriage WHAT should I do to scatter and put fire in her own marriage?
