I know what you struggle with...it is so hard not to focus on possible indications that there was an OW. Especially now when your r is so insecure, unsure.
But you know there is really nothing you can do about what he did. I mean really...what will you do with the info if it is true he lived with someone else? NOTHING....you can't change it or make it go away once you KNOW. So don't know THAT...know instead that your h:
1. dreams about you (though it may be bad he is getting how he feels out to YOU) 2. He thinks about ya'll together 3. He calls YOU 4. Invites YOU over 5. text messages YOU
ETC.
Come on, hon, it's YOU he wants NOW. Relish that, enjoy it, use your womanly power to make more of that happen. You are the best thing for him and he sees that.
let this other BS about addresses, suspicions, etc GO. Live for TODAY.
(that little pep talk helped me immensely too...I was struggling with the gal's phone # I found at h's apartment this weekend)
