I can completely understand how you are feeling. I only wish I were a member of this site when you posted. I went through serious depression for about a year and a half after being diagnosed because my partner denied any responsibility in the matter. It was completely my fault in his eyes, and for many months I beat myself up thinking maybe it was, made worse when he left.
The facts are, it isn't even a question of blame because FACT 1: the doctors explained that you could have it for weeks, months and never even know until that yearly PAP because many people are asymptomatic. FACT 2, if your partner is unwilling to discuss the matter in a mature fashion, then chances are your relationship was fated to end anyways because a relationship without open communication is bound to fail. FACT 3. As the moderator stated, we are all human. The best way to cope is seek out support among friends or those of us who have faced this same reality. By doing so, you will be able to not only gain your confidence back, but you will also be helping to reinsure their confidence.
DO NOT do what I did and close yourself off to the world feeling like you've done something wrong. YOU my friend, are not alone. I not only had a partner who blamed it on me but my doctor of 8 years turned* on me as well, making such statements as "that's what you get for unsafe sex practices" (even though I was engaged to my bf and together for 2+ yrs). My doctor, whom I confided in for so long suddenly was not friendly or sympathetic anymore, and believe me, I understand the sting that can cause. It took me 3 years to even go to another doctor for fear of how I'd be treated
You must forgive yourself (if you feel you need to do such a thing), and then move on. Keep your head up and be thankful it was curable and not something more serious. As for your partner, remind yourself that if you are not worth his time and consideration than you are far better off without him if he ends it. Always remind yourself that you're not the only one out there who has gone through this and just take measures to be more careful in the future. After all, that's all any of us can really do
