Well,probably she will. But,you are not going to do anything about it. So,dont torture ypur self. Just let her do what she wants to do and that is it. If you won't demand truth,won't divorce,wont do anything about it,why are you here? Just accept it as it is and live your life like you are living now untill you die of old age. Im not brave eather,but I would rather die that live my live in suspition and agony. So,if I were you,I would divorce her and find some lovely lady who would be a great mother to your douther and a loving wife to you. And you are forgeting one thing. What if she has her next affair with some single guy who wants to be with her,marry her? Then,in that wery moment she would be gone. She will divorce you and be happy with some other guy. Anf you,you will only be older and less atractive then you are now. So,dont be afraid,divorce and find someone to spend a happy life with. Dont torture your self any more. Live is too short to be waisted like that.
