Re: Wife says she need time alone.
Could be a massive sh_t test to see if you care about the marriage.
Could be she wants you out of sight to test drive some other guy.
Best advice I can give is tell her "If you move out, we might as well get divorced right away & save time".
Hard to have heart to heart conversations when you are living in different locations.
You can go on dates, etc, while living in the same place.
Check phone records, drop by her work unannounced for a lunch date. Is she seeing someone else??
PS- I read this quote on this site a couple of weeks ago. "Don't love someone so much, that they can use your love as a noose against you". You may love your wife, but you CAN live without her. Don't cry, don't beg, be firm.
