F*ck ..🤦🏻‍♀️

My ex of 4 years got a girl pregnant after a month and a half of broken up.. it’s been 8 month since we broke up and she’s due next month. My head is going crazy how tf does he do this. After this entire time he’s being continually telling me lies I didn’t believe it I CANT! But I seen pictures of the girl she’s definitely due next month. How tf do you get over this or cope with this
