That is a freaking roller coaster right there, but keep in mind she's pushing her guilt all over you. Making this about you giving up while she's running off to OM. Do NOT ignore this. Her guilt is not yours to carry, my friend.
She's clearly seeing the changes in you and that's great because she's acknowledging that they're real, not manipulative, etc. Just keep doing what you're doing.
We all end up in places we did not want before BD and not because any of us intentionally wanted our M to be that way. It is complete horse caca (haha DB censors!!!) to be throwing you under the Divorce bus as it's you're fault for giving up.
Hope you have a great day today.
