Heartbroken 😭

So I’m 14 weeks pregnant with my fourth baby. My world has been turned upside down. This babies dad has been lying, cheating and being devious for a whole year! He’s been in contact with his ex girlfriend on an account he made up and hid from me... talking to her and her children etc. He was also in a sexual relationship with another woman for 3 months.... he had 3 women on the go at the same time and I totally did not see it!! I’m devastated... I’ve cut him out my life, I will not have any contact with him at all... now I’m wondering how I’m going to cope with having his baby... what a position I’ve been forced into 😭
