I need some advice please!

After a long toxic and abusive relationship I decided to leave my husband this year 6 months ago, 3 months later I met this guy that’s been everything I wanted and more, I’ve been on the depo shot birth control por like a year, yesterday I was feeling so bad and I took a pregnancy test and it’s positive. I am so emotional and confused for the longest I tried to get pregnant by husband it happened just once and ended up in miscarriage. Now here I am still legally married in process of divorce pregnant by my boyfriend that I’ve been with for the past 3 months btw my boyfriend never been married and doesn’t have kids. He of course wants us to have this baby. I just don’t know what to do 😭
