Not sure how to title this one! Also, I know that laws/processes may be different as we are in the US vs the UK, but I wasn't sure who else to ask.
A friend of mine has a six year old daughter. She and her DD's father are not together but he has DD every other weekend.
The friend has just found out via his live-in girlfriend that he has been taking steroids for over a year.
Her concerns are A) the illegal nature of it, obviously and B) the effect on his temper/stability. He was jailed years ago for assault on my friend and she really concerned that the steroids will make things worse.
They've had a decent co-parenting relationship in the last few years and I know my friend would like to keep it that way, but her concern for her daughter (and the girlfriend as well) is more important.
What should she do first?
