I (32M) Had sex with my ex (32F) and she's pregnant, what do we do?

I (32M) split up with my ex (32F) 6 months ago. We were together for around 4 years. We have 1 child together already.

She stayed over at my new place about 3 weeks ago. We had unprotected sex (once in the 6 months being apart). She did a clearblue test today and she's 3 weeks pregnant.

She doesn't really want to speak to me about it. And has told me to leave her alone, which I have respected that.

I know a lot of the comments will say, You should have wore protection, you shouldn't have slept together... etc. I know all that.

Maybe if there's anyone on here who has experienced something similar can give some advce or insight into what they did, that would be much appreciated.

When we had our first child it felt exciting and amazing. And due to the circumstances. This just doesn't feel right.

I'm a big believer in a womans body is her right. I'm not anti abortion for anyone else. But at the same time personally I am against aborting what could be a perfectly healthy child.

At the same time it would be born into a broken family. Also there is health concerns to.my ex, because shes had 3 c sections already.

My heads all overplace, anyone got some words of advice?
