Hello, new to site so be gentle. I have been with my husband for 17 years and we have a 15 year old daughter. To keep things short my mother in law died 2 years ago as a result we went through a rough time. Things are a little better now however I have suspected my husband is having a affair for a while. When anything happens like his hair smelling of coconut shampoo, which I don't have in the house, happens I kind of wash over it. But I am stewing on this all day every day. I keep telling myself that unless I know for sure what's the point in running everything. We don't have sex hardly ever anymore despite my best efforts. I keep thinking it's me but I am in the best shape of my life at the moment. I have tried talking till I am blue in the face I have told him I will leave if nothing changes. I don't think he believes me. I am only 34 I can't go on like this much longer. Please help. Should I keep brushing the signs under the carpet?
