You can be not okay with her sleeping with your husband. Or you can be not okay with her seeing other people. Not both.
You say she's okay being monogamous with you. .. even though you treat her as something on the side. Clearly she isn't, or she wouldn't have gone on a date. She has needs you won't allow her to get met by her boyfriend/partner. Fine. She's allowed to get those needs meet elsewhere. And you freak out over a KISS? ??
What she has demonstrated is a clear patience with you..... but if you keep being unreasonable and controlling, she'll probably leave. Or start ignoring you completely. I would if I were her.
Also she's a person, not a pet. I agree with pulliman. Don't call her "your" third. Not only insulting, but implies you own her.
