I am a single FT working mum. I earn a decent salary , work hard and am happy at work. I manage to look after DC without any financial or childcare help from any members of my family or the exH. Admittedly it is hard, but I cope. My exH left us 4 years ago and moved abroad. Around the same time my SIL (brothers wife) willingly left her well paid job to look after her children. My brothers professional career in the meantime has gone from strength to strength and I recently learnt that what he earns in a year I will never earn in my lifetime. I know he deserves it, as he works very very hard, but a small part of me feels a failure in comparision and not as lucky as SIL in terms of the choices she is able to exercise. We all three achieved good professional education though in different fields. My rational mind knows it is unfair to make this comparision but emotionally cant stop feeling so.
