My neighbour is a lovely young woman in her mid-20s. She has one baby DD and an ex DP who is on-off-on-off with her.
He lives in his own house not far away and dips in and out of her life...he pops up more often when she has money. 
She's beautiful and would be able to meet a much nicer man but she continues to hope that he will get it together and move in with her. She doesn't see that he's shite and never visits their DD regularly or contributes. I want to tell her to go out a bit more...meet some nice man who will be more committed.
But you can't can you? What advice do you have for people in your life that you just can't give?
