Lovebunny, thank you for the encouraging words.
I'm definitely seeing things a bit more clearly now and the bottom line is that I didn't know either of them well enough to trust them. In my opinion, real relationships of any sort aren't built on a few months of Facebook messaging and a few real time visits. The depression made things worse and clouded my mind quite a bit. I'm going to take your advice and just focus on myself and my marriage for awhile.
