a guy at work has recently expressed his attraction for me; I'm a single mum of three; he has no kids but would like them. He has indicated he would like us to have some sort of relationship; one that it is secret; and I guess pretty casual? There is definite chemistry there, but I am concerned with making things awkward at work if it turned sour. Not sure what is in it for me really, aside from some risky casual fun? I am late 40s. he is late 30s
