What do you guys think?

So I recently found out that I have PID it had developed since my last relationship (that lasted 2 years). Before that relationship ended I went to a gynecologist and the doctor told me that I was okay and everything was cleared. Today I have moved on from the relationship and decided to share with my current partner this situation. Because I didn’t want to lie to him or make him feel like he can’t trust me. He told me he understood and that he hoped I felt better. But today he said something about it and laughed. Then said “ay just be glad I can laugh about the shit” it broke my heart. I asked him if he was always going to joke about it because it hurt my feelings and he said “sometimes, because you were careless just sleeping with him. That relationship was probably filled with a bunch of red flags” looking back at that abusive relationship I was in yes it was. I went home crying because I really trusted my ex. We were together for 2 years and sometimes we’d have a condom and sometimes we wouldn’t. I’m just glad this thing is curable.
