No you are not weak. Many of us have experienced false R. You wanted to believe what your WH was telling you because you love him and trusted him. Mine did the same. I did not get the full info until 6 months later, which I found on my own and when I confronted with it he had no choice, the truth was in his face.
Take your time. I think you are strong for making him leave the house. Keep up the great work and watch his actions. Mine gave me tears and he never cries but then broke NC with MOW so I'm not sure how genuine my WH's tears actually were.
