Hi Nina, I'm not an expert on this but most of the May settlement applications were completed in the last 10 days (according to this blog about 4-5 went through) so it's looking like you are having a longer delay. I think also the Embassy only need to decide on the "means to support" rather than the "genuine relationship" aspect.
Some people on this site have emailed directly the British Embassy and they often get some meaningful progress info quite rapidly, so this is worth doing.
I hope you get some good news soon. I think Joebloggs has some posts on this blog with lots of information.
