DD is in her 20's, has a degree and is in full-time work. Having DD living at home is like sharing the house with a lodger: a lodger you don't get on with very well! On a typical weekday we might be in the same room for 15 minutes at breakfast and another 15 minutes at tea time and that is the extent of the social interaction that takes place unless DW or I go to DD's room to initiate it.
DD never makes any gesture of affection towards us, although she does towards her long-term boyfriend, she never starts a conversation and doesn't appear to notice that our entire daily routine is based around her convenience.
It is really starting to grind us down mainly because any attempt to resolve or even talk about issues results in tears and sulking by DD.
Any ideas or practical tips?
