to be suspicious of my sbxh?

[Simile]

The sbxh left 2 years ago. He sees the DCs regularly but rarely has them over night (2-3x a year). He wants to remarry. I've agreed verbally to a 2 year separation divorce if he's the petitioner and pays the fees. But he wants me to sign a solicitors letter saying I give my consent to this type of divorce.

Thing is I lost my trust of sbxh when I discovered the string of affairs he was having. He looked me square in the eye and lied about it all (classic I know).

So any ideas why needs this letter? He says we don't need to reach a financial agreement but this is the most important aspect, particularly as I'm a mature student at the moment and will be for another few months. At the end of my course I no longer have my bursary to pay the mortgage.

AIBU being so suspicious? I've lost my perspective.

Quick update: I now have a Shit Hot Lawyer who got my situation instantly (he got a twinkle in his eye and did a little smirk when he saw who the ex's solicitor was too). SHL wants full financial disclosure and a financial settlement before we do the two year separation divorce. SHL said ex has no cause for unreasonable behaviour so couldn't go down that route anyway.

Thank you all for the advice and support, I really needed it! SHL will be worth every penny and I've been sleeping so much better!

That's brilliant, well done Simile!

Now you just have to remember that SHL is the one to take advice from, not your ex, and brave yourself for the tantrum your ex is likely to have when he finds out you have SHL on board! Good Luck!
