had an 2 year on off affair with someone ive known for 17 years. Were both married and both have kids. His are 4 and 7 mine is 8. I dont know what to do now its over. I dont know if i should stay with my DH or leave. Me and DH have discussed going separate ways anyway ( he doesnt know about the affair). Our sex lifes pretty non existsnt been like that for years and were only young. At the moment i feel suicidal about it all. OM ended things even though he instigated and pushed for it all. Do i tell my DH? I think that would cause unnecisarry upset to him and the household but i dont know how to move on.
