Ladies... I've met this guy but is ex is 6 months pregnant.. Advise?

I've met this guy and his ex is 6 months pregnant with his son. I don't know why they split but I'm pretty sure he left her. The thing is he has told me he will carry on supporting her and he will be there at the birth and for the 1st 2 weeks when the baby is born. Is he just a good guy? Or should I be careful. 😐
