Hi BT -- Thought I'd post to your thread because I'm pretty much in the same place as you today. My stbxW is also very angry, does not love me anymore and I believe would be happy to see me living in the back of my truck and eating from dumpsters. (Why? after 16yrs. and raising our D together I'll never know) I was unsure of how the courts here (Can) would respond to her requests in the seperation agreement.
I realized early on that I had no control over the outcome of the process. The only thing that I could do would be to be honest about our financial situation and express my desire to be fair to us both. The good news was that the judge was able to see how completely unreasonable her claims were and said that it would be best for all involved ($$) to accept my fair offer. Will I be retiring early? No. Do I get the new car, boat, cottage that I wanted? No. Does my life proceed the way I had expected it to? No.
Will I have a roof over my head? Yes. Will I be able to feed myself and keep the lights on? Yes. Do I have an opportunity to continue my life, be happy with what I do have and hopefully meet someone who will love and respect me? Hell yes?
Don't get me wrong, I wish I (we) didn't have to be in this place. What I'm trying to say is, I will get through this and so will you. Have no fear. Be honest, be fair, be a good person and good things will come to you. Hang in there BT, you'll make it!
