Hang in there girl. I have been feeling like you over the last couple of days. It has been 8 months since I found out that the W was considering leaving and nearly 6 months since the bomb. I am getting weary. I don't want to mess up the hard work and gains thus far but it wears on me. It's the get your cake and eat it part that festers inside me while my needs go unmet.
Something to keep in mind. I read that if you are not sure if it is going to work out, you want to leave your spouse with good memories. If you split then maybe the WAS will see what they are missing. They might realize the grass isn't greener.
