Still inlove

How to get over someone if you’re still sleeping with them . I’m no longer with my babies father and I’m currently pregnant and I still sleeps with him . There’s another woman involve , he was with her before me. I can’t help that I’m bitter and I hate that woman so much because of him . Instead I’m growing apart I’m growing closer . I do things like stalk her page and get upset when she post pics of the both of them . Guys I need a life 🤦🏼‍♀️😩😩
