I have been separated from DS's father for 2 years now, best decision I've ever made! I now have a new partner and we've been together for around a year and a half although we have been close friends for about 6 years. We don't live together and DP doesn't ever try and act like DS's 'new dad' or gets involved in parental duties etc. I still feel like a lone parent although I also feel a bit guilty as I'm not technically single and have the emotional support from DP.... What does everyone else think about this, would you still class yourself as a 'single parent' even though you're not single?
