i have been married for the last 15 years(its my 2nd marriage) and just found out that my husband has been cheating with my 27yo daughter(note;she is not his biological daughter he is her step father).apparently it has been happening behind my back for the last year or so I found out through a friend she only just found out recently and told me asap as soon as I found out I confronted my husband about his affair with her his response was 'it only happened twice' following his response I asked him to pack his bags and leave he has tried contacting me since I booted him out but I don't want a bar of him I also confronted my daughter about (who is married herself) it and her response was 'we didn't want to hurt anyone so we kept it a secret' I too haven't spoken to her since last week I have only told a few people about this but I feel so let down and betrayed by them both I am considering getting a divorce this has truly affected me and now I am just angry,shocked and hurt how do I deal with the both of them?
