Pregnant and dumped

It's been really hard this last week. Ex broke up with me and ended up having another woman come over after he kicked me out in the same day. Now all I hear are lies coming from his mouth. How can someone just talk so badly about someone you told every single day for a year and 4 months you love them and just do that? Trying not to stress but I need prayers and advice this isn't easy, he's really making this difficult. What to do?
