I'm really sorry twixi, recurrent mc is soul destroying.
Your oh's reaction sounds very normal. In the end, we worked out that we couldn't talk to each other about how this was making us feel as we'd never try again, and there are all sorts of guilt issues (I felt guilty i couldn't carry his baby, and he felt guilty for putting me through it over and over). Both of us got separate counselling and it really helped.
The other thing that helped us both loads was to stop changing any plans, short or long term for "what ifs", we figured that cancelling stuff (even losing a bit of cash having to do so in some cases) was preferable as we would only be doing so if we had our "keeper".
