I'm the other woman and I'm sick to my stomach 🤢😞

I met this guy nearly 3 years ago. He had a girl. I was fully aware. I didn't pursue him or anything. However we became friends. Even she became a friend.

A year and a half ago, for whatever reason they broke up. When they broke up, he and I became closer. We'd grab lunch here and there, had bunch of people over for a hockey game, whatever. Still friends, nothing sexual or romantic up until roughly 6-7 months ago.

So started seeing each other nearly 7 months ago, things were going well. I fell for him hard. He was the piece I never knew I was missing.

Three weeks ago I peed on a stick that read 3-4 weeks pregnant (I know they aren't super accurate but the point is I'm pregnant and super happy!)

I thought he would be happy too! Until I saw him turn pale like a ghost and say well fuck shes gonna kill me. I was like who? He was like ------ (his ex)

I'm like why does it matter what she thinks? He's called me an idiot and said they were still together she was just in Europe doing an exchange program for 2 years. And that I was just filler to keep his dick wet.

I was so crushed so hurt. In a split second my world came crashing down. Now I'm almost 6 ish weeks pregnant - my first appointment is next week. I've never felt so alone and confused and hurt all at once. What do I do?
