I continue to live in fear

The first marriage was unsuccessful, we broke up, but I have a wonderful son. The second time I got married in 2010. We met on the Internet. He's a fine man, three years older than me. We signed a month after the acquaintance, in a year our daughter was born. Everything can be said splendidly, but there is one thing ...

My husband's mother died long ago, only my father remained. At first everything was fine. I had warm friendly relations with my father-in-law, I found, as it seemed to me then, a father, whom I always lacked. But I was cruelly mistaken.

Three weeks ago, my husband went to the hospital, and I stayed with two children and a father-in-law at home. At night I woke up because I heard a heavy breathing above me. I was frightened, because my husband was not at home, at first I thought that someone had climbed into the house. Imagine my surprise when I turned and saw my father-in-law. He was not even embarrassed by the fact that I stared at him. I asked him what he needed from my bed. He began to admit to me in love, etc. I tried to kick him out, but nothing came of it. I was saved by the fact that my son woke up and came to my bed. The father-in-law turned around and left, and in the morning, as if nothing had happened, he came to wake me up to go to my husband's to the hospital. I immediately went to my mother after the hospital. I do not know what to do: tell my husband about it or not? Tell me please…
