What do I do with this secret, it's killing me?

For years my maid has been telling me how my neighbour's maids keep running away because her husband pesters them for sex.

I brushed it off because the guy is so Christian and respectable to cheat and moreover with maids.

However, recently as I was chatting with his wife, she lamented about having lost the only maid she managed to keep for almost a year.

She told me she suspects that her maid was pregnant. And the moment she mentioned that, I couldn't help but to suspect her husband being responsible.

I was so tormented that I asked my maid why that particular maid had left. She confirmed my suspicions. She told me that they've been sleeping together for some time and the maid has been openly bragging about it. Worse still, the guy forced her to abort twice.

When the he forced the maid to abort the 3^rd time, she decided to resign.

Meanwhile the wife keeps on asking me to give her tips on how to keep maids for long.

It broke my heart when she told me how she misses that particular maid. According to her, that maid was the best she has ever had.

There I was listening and dying to tell her the truth.

I'm so confused and so scared that I might be tempted to spill the beans. So I find myself avoiding and she has realised it.

What do I do good people?
