You have to decide for yourself. What if you find out that she's cheating. Will you leave her, or will you just feel bad for knowing? If you'll leave her, then investigate and you will probably find out pretty quickly. I think she is cheating.
Given that she cheated with you, multiple times, it seems unlikely that she is ready to adopt a mature attitude about her commitments to her family.
Good luck.
