Think I'm going to be a single mom

Been together a year and some months now...

Found out I'm pregnant and told him.... He said he's happy and sad... Happy because it's his first child but sad because he's married... I'm just finding this out... Apparently him and his wife have been trying to conceive but it's not happening...

She's in another country hence the reason I didn't know he's married...

I'm lost, sad, angry... But abortion is not an option... I'm going to be a single mom
