Are any of these emotional cheating?

I posted these before but they still bother me: 1) instead of a guy friend, a woman that i had tried to befriend before was the one who drove my husband home. it was almost 1 am and they parked in front of the house for several minutes. i went out, thinking i was about to see my husband and his guy friend drinking. but no, it was that lady and she did not go out of the car to say hi. my husband went out with a grin on his face. he later got mad at me for being mad that he came home very late from an event. he claims that she was sharing a problem about his guy friend, who is supposedly not being a good supervisor to her 2) my husband and another co employee (a woman rumored to be having an affair with the guy friend in #1) have been taking pictures of each other in town. i did not know about it until i saw my husband's solo pics in her instagram. she and i are friends on facebook and she did not post there. i innocently requested her to add me on insta and that is what i get. she said she has pics of the other guy as wdll (they are also both married to different people). she also took a selfie of her with my husband driving the company car. he said he did not know about the pic. about a week later after i confronted the woman about the pics in a nice and polite way, my husband was terminated from the job. she was the oic. good thing my husband immediately got a new job afterwards. My husband has no contact with these people again but I am troubled with trust issues because of what had happened. The woman in #2 passive aggressively posts about me and my family on FB and views ALL my pics on FB Story
