Fidelity is always a choice .... not necessarily an easy one, but maybe she needs to stop thinking about her feelings of this moment and start thinking about how she will feel if she makes a choice to be with this other man ... how will she feel when she has to tell her husband about it ... who she freely admits she still loves, how will she feel if he cannot deal with it and asks for a divorce, how will she feel when her child looks at her and asks why daddy doesn't live with them anymore. When it comes to the hard choices in life ... I try to think it through to the conclusion and ask myself about the things I might have to deal with ... for me, looking myself in the mirror everyday thereafter would also have to be included in the possible future I would look at.
