I am giving her space and I have backed off I wasn't sure if I should go totally cold or not at this stage. Earlier in the thread there was talk about finding the right balance so when she comes to kiss me I kiss back. When she says ILY before going to sleep I say it back. I am working to stop the over analysing everything she does as it drive me mad as I try to figure out what does it or what doesn't it mean and I am just trying to focus on the day to day for now.
What threw me for a loop was all the initial positivity and affection and the "this will be a better marriage" back to not being sure what she wants. Whatever the reasons for the back sliding I am sure it will reveal itself or get better with some time.
