STBX got the letter from my attorney today stating we are expecting her to go back to work (she was SAH mom for last 3.5 years) and she will only get 2 years of spousal support due to this being a short term marriage (6 years). She has gone from texting me yesterday about how she's sorry she cheated on me, she wants to work on rebuilding trust, and she loves me. Today it's full rage and saying she's going to make things very difficult. Any advice for those that have been through this?

Feel free to read old posts to get to know my story.

Notes: I'm high income earner. She has no education and never earned over $50k/yr. Was a stay at home mom for last 3.5 years. Had a 6 month affair and left me for AP but that ended (or so she says) 3 weeks after moving out. 2 kids and I'm seeking 40/60 while youngest is in preschool and 50/50 once youngest starts kindergarten
