My Mum Insisted She Must Go! Help

Hello , just became a fan of yours recently keep up the good work dear. I have a problem I need to share with you for Google counselling.

I was introduced to a girl by my brother's wife, she told me how et have been very close from school and how good she is,because how good that my brother's wife is,I told her to bring the girl to me and that was how we loved each other and started a relationship immediately we met. Yes she is very good,kind,generous but when she gets angry she can move mountains within two seconds. I do t know this part of her anyway until she got pregnant and I went for her Introduction and engagement. It was a successful party and our wedding is scheduled for July.  Few weeks ago, my ex girlfriend called me on the phone and immediately my wife saw the calls,she started shouting,

I told her that I don't have anything with her again. She said then I should have blocked everything about her, an argument ensued and during that period my mum walked in,she came to see if we are fine. She lives in the next four street though. She met us quarrelling and interfered that my wife should stop all this nonsense. Instantly, she shunned my mum and told her to go back to her house that this is husband and wife matter. My mum picked her purse and left immediately.

Ever since then. My mum has been disturbing me to drive her away. She said for no reason should I marry her again else she doesn't want to see me anymore. Have pleaded but she insisted that Eno must go! Please no matter what,I love my wife and can't afford my child to be born outside, help
