I slept with this guy that i didn't know was still seeing his ex and he slept with me and her the same night . I caught pelvic inflammatory disease off him and he didn't tell me he had it.Well i had the disease for 2 months without knowing it and i ended up dating somebody else why i had it and i had sex with him unprotected. Anyways my question is did he catch it?Can he catch it?Should i tell him to go get treatment.
