I found myself wrestling with the same question. Although I did find some questionable texts. That is all I found besides a card where it is clear there is nothing going on but the girl is willing to wait and see. At any rate my husband has stopped communication and as time has passed I have encountered nothing to make me think there was an A at all. In fact to the contrary I have found more evidence that there was nothing. However, at the same time I did damage my R with my H. He is very hurt I suspected him. Even though he played a HUGE role in the accusation.
AT this point I need to just move forward and work on our M. I know that I want to be with my H the rest of my life and I know he is suffering from other stressful situation besides this one. So now I DB and pray and hope for the best. At this point it does not matter to me one way or the other. I am standing.
