unreasonable behaviour...have i left it too late

[Minime85]

kept putting my divorce paperwork off and busy with work etc. anyway just sat down to do it and I'm now panicking I've missed a 6 month window it seems for unreasonable behaviour?

he left start of November , his decision and we agree on getting divorced. not using a solicitor to keep costs down. because it has passed 6 months since he left, does that mean I can't use anything from before that for unreasonable behaviour?

Don't panic! The six months only applies if you have reconciled for six months since the last incident of behaviour. If you've been living apart (even at the same address), then you are fine using the pre-separation behaviour.
