how do i keep my hope alive?

Keep doing what works - what the books says - Respond to him - but don't initiate. Limit interactions

I really don't think that is what the author is saying.

Yes, this is what MWD is saying.

p.99
Step Number 4--Stop Going Down Cheeseless Tunnels
"But the truth is the only real failure is to keep doing what hasn't been working, and, if your marriage is teetering on the edge, doing more of the same is downright dangerous."

p.130
"The general rule of thumb here is to be responsive to your partner's new interest, but not too responsive. If you go overboard, your partner will get cold feet. I've seen it happen many times before. If you are excited that the last-resort technique is working, share it with a friend, write it in your Solution Journal, go for a run around the block, but don't wear your emotions on your sleeve.

You need to stay interested, but cool, until you are absolutely convinced that your spouse's renewed interest in saving your marriage has taken hold. Once you feel absolutely sure that this is so, you can test the waters by becoming more obvious about your desire to stay together."

TTA, are you absolutely convinced that your H wants to save your marriage? If not then stick with what you have been doing so far that has been working.

And yes, I think you should definitely be using the Last-Resort Technique.

p.124
"It's imperative that you begin doing the last-resort technique immediately if:

• Your spouse has said to you in no uncertain terms that s/he wants to get a divorce and it appears as if s/he really means it. It wasn't just said in the heat of battle.
• You and your spouse are separated physically.
• You and your spouse still live together but have very little to do with each other. You may be sleeping in separate rooms, have virtually no communication, and little or no sexual contact.
• Your spouse has filed for divorce."

Your sitch fits both of the first two criteria.

I totally agree with talia's advice.
