Hi Buddy. Before all his drama was your b/f (husband) treating you any differently? I know you said he is now, but was he different before you decided to confront everyone? I ask cause maybe he is was telling the truth about his relationship and maybe he knew you would cause a problem.
If I am understanding right this man has has affairs while being with you..or did he have numerous affairs before he met you. Affairs before he met you in my opinion have nothing to do with you. That is before you!
What should you do....mellow out and see what happens...if you do not have trust then you should not be there anyway!!!
