actually there is no clinical difference in recurrences in bv in the female when you also treat her male partner. It's not recommended to treat the male partner when the female has bv - even when it's frequently reoccuring bv.
How has your provider been testing you for bv? If they are looking at your vaginal secretions under the microscope - ask them if you have "enough" of the "good" lactobacillus bacteria too. If you are lacking protective "good" bacteria there is a product I can recommend for you.
You also might get some benefit from your partner wearing condoms if you don't already. The ph of sperm can throw of the ph of our vaginas enough that vaginitis can continue to be an issue.
Bv can really suck sometimes
Also sometimes treating it can just trigger the ph to go the other way and you get yeast and sometimes it's just a tricky cycle to get out of. You can also ask your provider to look into some long term bv treatments and perhaps ask them to do a pubmed search on some of the newest recomendations on treating bv with more than one medication at a time too.
