I don't know what to do..

So my husband and I have been having really really bad problems... don't want to go into detail over it but I got on the whisper app and started talking to this guy about my problems (stupid I know) and I told my husband I done this and I was sorry and he said he deserved it and this was his fault etc because of some stuff he said that really messed us up... anyways this guy on whisper I ended up blocking him on there and deleting the app but I can't stop thinking about him... he was so sweet and wanted to take care of me and make me happy not to mention he was beautiful... I don't know what to do... I feel disgusting...
