My solicitor is not adverserial and clearly is uncomfortable upping the ante if it's not necessary. is it time to change tactics - or even solicitors?
Here's the background:
My ud-BPDh left the family home last August. I asked him to leave after he said he didn't love me anymore and wanted to separate. Once out of the house he started to protest that I'd thrown him out. I then asked him back and he refused saying he never wanted to be put in this dreadful position again and wanted a divorce.
We both went to see solicitors and I hoped to be able to solve things amicably using collaborative law.

. My sol is trained in mediation and collaborative law but his is not and it soon became apparent that he was not inerested in this approach. His main interest was to get me to sell the house.
Once he found out that he could only do this by divorcing me, he collected our marriage certificate from the house to begin divorce proceedings. Christmas and New Year came and went. (He was very angry that I didn't invite him to spend Christmas with me and the children - they asked for us to go to friends).
Meantime, I've been going to therapy which has been hugely beneficial in helping to straighten out my mind (originally on my BPDh's insistence because I was mentally derranged). By February, with the help of the therapist, the fog was beginning to lift and I realised that he was having an affair - he might have been having several affairs over the years. Two days later, a friend reported seeing him with another woman (and a child) at a Christmas panto in our home town. I then received a few of his bank statements via my solicitor which showed clearly that he'd been staying in expensive hotels in the months leading up to our split. I emailed to ask him if he had indeed been having an affair. No reply and two days later he filed for divorce for my unreasonable behaviour. I asked my solicitor if we should counter petition for adultery, but on his advice I agreed to accept the divorce (though not the grounds) and signed the papers. We are still waiting for my bph's sol to submit the papers for the decree nisi.
Until now, I've kept things fairly low key with my sol and havn't mentioned the words BPD. I've just told him that my BPDh is a very difficult person. And his behaviour is proving that to be the case. But now I think it's time to get tough. Things have been dragging on too long (because of my BPDh's lack of ability to get on with things), and I just want out. How do I persuade my solicitor to 'up the ante' without seeming like the mad woman who wants a high conflict divorce? Do I show him, Splitting by Bill Eddy (excellent book) which advocates a very assertive approach? I live in the UK so his work is not widely known but at the same time I don't want to 'teach my grandmother to suck eggs'. Advice please!
