I've been a stepparent for approx 10 years now. When I met my husband and he had two daughters one was almost 2 years old and the other was 4. Their mother basically up and left from Texas to a pacific island and did the absolute minimal amount of work to be considered a mother. After a few years all contact was abandoned by her and they haven't seen or heard from her for at least 6 years. Neither of them remember much about her. 

FWD to now:
