Dr Appt no support

Today is the day I find out if I'm having a Boy or Girl. My SO and I split about 3 weeks ago and got in a big find last Thursday who knows the appt is today and has yet to acknowledge it. I can't understand how someone could walk away from there family and for some ass and not look back. It's ok I'm gonna go today and find out and be a PROUD SINGLE MOM of a Healthy Baby. SCREW HIM but it still hurts.
