There’s not much I can say apart from this as a side note:

As the daughter of divorced parents (partly from infidelity), I felt incredibly loved, enriched with an amazing childhood, and lucky growing up, I knew even if my parents weren’t in love anymore, they loved me, and it taught me a lot of precious lessons over the years. I’m definitely glad they didn’t have to stay longer in a tumultuous and loveless marriage and thrived in their own directions. The majority of my friends are also from divorced households, we share the same sentiments.

I hope this can give you a little bit of extra strength and confidence in the process (regarding your two children), and good luck.
