This is a Message for (N) from Peter in answer to your question.
It is a difficult one for Us as We can see where you are coming from. You feel that (M) needs looking after and you are in the best position to do it.
Actually (M) is more capable than you think to look after herself. That said, you two need to be together for a while yet to complete your Mission. Actually it’s above and beyond what you were destined to do but this has brought strengths from you both to the surface and the Path is still on the right track because of you.
As to the future We can’t say, it depends on too many things. Only know that because of your dedication and one pointedness you will both be looked after.
