Divorce proof hearing Scotland

Please help ! After 9/10 yrs and 3 option hearings and 1 peremptory diet, I have dates for a proof hearings oct and November . My x will just not give in, all that's to be decided is army pension, married 30yrs the whole time pension was running, sperated 2002, solicitor states I'm entitled legally to half his pension which he has had in payment since 1993. But he still won't just give in and accept this , so now it looks like he is going to let it go to proof, I'm worried sick now about the costs , 1. How much roughly will these hearings cost, 2. If he is the one defending and won't budge on it, who is responsible for these costs , 3. What actually happens at a proof ? I'm getting so stressed now I just want the judge to see I have done everything the right way and all I want is to be free, on the other hand all he wants is to keep stalling it. I am full of anger that his lawyer hasn't advised him that legally I have a right to a percentage of his pension whether it be 50/50 or whatever.
