It does appear to me that your relationship with your IP has broken down, and if you do not feel that she will listen reasonably to your position then I would go and seek independent legal advice locally. I assume that you live in Devon, from the location of your IP, so could I suggest you contact Stephen Lawson of Foot Anstey in Exeter. Stephen is a leading lawyer in the field of IVA's, and a short consultation with him, or one of his colleagues, where they can review the paperwork to see exactly what your contractual responsibilities are ought to at least confirm the position for you.
As you are only offering 13p in the £, I do have some sympathy for your IP's position and I can see why she may be concerned that creditors will not accept your offer, but this could have been renegotiated at the meeting at which time you would have had the opportunity to consider submitting an incresed offer.
You are obviously aware that if creditors do not accept your offer, then bankruptcy proceedings are inevitable - during which you will be made no allowance for the relocation costs. So please do tread carefully.
