Had my day in court and it was all bad….

How can a man you’ve been with for five years just up and leave for someone new and leave you pregnant with twins (first kids for both of you)? Even took my car and drive to her house to spend the night. Came to your house, took a shower, got dressed, and sneaked off to see her! To top it off he asked her to MARRY him after only 3 months! But I’m supposed to be happy to let him take my kids 50/50 AND change their last name! Today was a horrible day in court 😢. How do I get through this?
