I Was A Very Good Girl So Why Did God Allow This To Happen To Me?

Please hide my identity. I am 35 years old with a year old son.
I met my ‘husband’ in 2013 and we started our relationship in 2014. We ended up married in 2016 June and got the great shock of my life a couple of months later that my husband was already married with a daughter. I later discovered I was pregnant, from that point on my life has been one long miserable story.

The man I adored and trusted deceived me with his family. They claim he said nobody should tell me the truth simply because he loves me and didn’t want to lose me.
Everybody believes I am happily married however I live like a single parent. I feel alone and miserable because I grew up with a single mother and I saw the psychological and emotional hardship she experienced,I promised myself that I will give my children a better life but this is where I find myself.

Now the liar is not going to let me be, I want a restraining order against him however my loved ones says the marriage should just be annulled traditionally so am free but I should allow him come around because of his son.
What should I do?

I want to move on and erase him from my life,by doing this I can be healed.
NB.. I just discovered that he has a second child with his first wife so him saying ‘I don’t want to lose you’ does not hold water.
My strength is failing me, am in a tottal mess. I was a good girl, I kept myself and now this
Worried Lady,
