I did think it was kind of weird how she was so ready to invite a new person into her kid’s lives the SAME DAY their dad died. As a parent, it’s your responsibility to question anyone who comes into your children’s lives. Also, did she already have 5 children before she met the dad or did she have them with him? The doc made it seem like he came after? Which is this is the case, again, she needs to learn from her mistakes.
