Trying not to stress

Just broke up with my bf and I'm trying not to stress out about what's next. I'm having twins and I didn't plan on being single I thought we were going to get married. However, I'd rather be single than to be married to a lying cheating sob. That being said is there anyone else out there that is single and just trying to hold it together? Ik it'll get better but it's extremely hard when your emotions are all over the place.
