After I had an induced labor, my husband regretted his infidelity

At 35 weeks of pregnancy, I had an induced labor and the child died.
My husband said that I should take good care of my body, and we hadn't had sex for more than a year.
During this period, he took meticulous care of me and comforted me, saying, "As long as we live a good life together, nothing else matters."
Until I accidentally saw the WeChat messages between my husband and an intern.
"Will you accompany me on our anniversary? Today happens to be my ovulation period~"
"I bought the lace you love the most.
Waiting for you."
The last message was a kissing emoji.
