As someone who has similar issues I can tell you this raises red flags for me immediately. My husband & I both had issues that required treatments from specialists for more than 2 years.
If SHE had problems that were diagnosed, why would she believe she'd get pregnant with
another partner?
The average couple dealing with fertility issues
typically (I do realize this is a generalization) turn toward one another for solutions & comfort until all avenues of testing are exhausted. They
generally turn away from one another as a result of ongoing failures separately/together over a length of time because it's not unlike dealing with the loss of a child to face that type of constant loss/disappointment.
Even if it was a primary issue, no WAY it's as simple as she wanted a baby & decided to start cheating on her husband - I'm not drinking that kool aid.
