MY MOTHER HAVE TAKEN OVER MY HUSBAND: Sometimes life seems to be wicked.

I am four months pregnant and doctor advised i stay on bed rest and avoid sex entirely because of bleeding. Hubby was in the hospital with me and he heard all that.
He was the one said my mother should come over and stay with me. I agreed. The next thing was hubby vacated our room to another room with the excuse of not getting tempted.
I started suspecting hubby not quite long but I couldn’t place my hands on anything as my mum is a deacon in church.
On Thursday I pretended to have gone out in search of mango but I was in the toilet in my room. After 40 mins of staying there I didn’t hear their voices again, headed to my mum’s room and my lawfully wedded husband was on top of my mother.
My mum is 56, hubby is 32. What is hurting me more is that my mother said I should be grateful she is holding him out of cheating so I slapped her and hubby hit me back.
I have left the house to a friend’s place, I have told my sister because our dad is late.
What do I do from here? Should i just abort the baby and move on to go deal with both my mother and husband?
You have brought up a very great details , regards for the post.
