Fiancé left me and got pregnant

r/

My girlfriend (28F) of 9 years whom I was engaged to for the last 4 years decided she was no longer in love with me. We have 2 children, one of which is not my blood. I met her on tinder and she was pregnant at the time. Father was a nobody and after a few dates I decided to fill that role. Life was good with its ups and downs and we even decided 3 years ago to have our son. In August she kicked me out of our apartment. Within 3 weeks she was talking to another guy.

I have missed her everyday since, it’s now march of the following year. I still have frequent contact with her and we co-parent our children. We have had many conversations both through text and in person about our relationship and it involved a lot of me pouring my heart out. Last week she dropped a bomb on me and told me she was pregnant. Even with this information I still wanted her back and would father child number 2 of not my blood.

Through the last few months there has been very slightly hints of flirting from her with me and now a week after telling me she’s pregnant, she has sent me nudes. She has even hinted she would have sex with me. She is still talking to the father but I’m not sure how good their relationship is.

I want her back, I’m willing to except everything that’s happened since the break up. Im so unsure what to think or do at this point. She isn’t asking for me to come back, however she isn’t telling me go either. What is really going on?

TL;DR: Looking for advice if I should continue trying with my baby mom. She left me and got pregnant the month after. She sends me nudes and hints at having sex with me. Should I move on or keep trying?
