I am sorry you are going through this. I know it must be heart wrenching, especially not having any control over the situation. I hope she comes to her senses and at least tries to work things out. 30 years together is a long time to just throw away without trying. I wish you the best. However, if she said she needed space, I would try to give it to her, even though it may be difficult to do so. I would not be able to, and that is probably why I will end up alone in life. But, I get what you are saying...is not doing anything showing her you don't care? Does she think that? I would ask her...tell her you want to fight for her and your relationship. I personally think she is being somewhat selfish and immature by moving out and saying she needs space. I don't know all of the details with the relationship, but did something happen to make her want to leave? To your knowledge, did you do something or was there an argument or is someone being unfaithful? I hope things work out for you.
