There is one thing you can try and it worked well for me although it is very hard to do. Cut out all "needy" behaviour. It is a big turn off to LDs. Never beg for affection because it has the opposite affect. I had the habit of trying to kiss and cuddle my W every time she came near me and she would instinctively push me away. I was not giving her any opportunity to show me affection because I was always there first. I have cut this out almost completely even though my arms are desperate to cuddle her. I have not told her I have changed my behaviour but she has automatically changed in response to my change. Obviously if someone is used to getting a lot of attention (even if they don't appear to like it) and that attention stops they will miss it and seek to get some of it back by initiating cuddles, kisses and even sex. It does seem to work. SD
