got chlamydia from a partner who swore they were "clean" — what now, like emotionally and practically

this is hard to type. F37, dh and i have been LS abt 3 yrs. we played twice with a couple from a club, both times condoms, but i did go down on him both times no protection (i know i know). routine test 3 wks ago came back chlamydia positive. dh tested negative thank god. i told the other couple immediately and they were like "oh shit thanks for telling us, we'll test". no apology, no acknowledgment that they prob lied to us bc we'd asked when their last panel was and they'd said 6 wks before. took my doxy, retested, im clear now. but emotionally im a mess. i feel dirty, i feel ANGRY at them, i feel like an idiot for letting my guard down on oral, and im scared to play again. dh has been amazing but he doesnt fully get how violated i feel. has anyone else been thru a "trust betrayal" sti situation and how did u get back to playing without feeling paranoid every time
