So I have an fwb who I haven't seen in a while due to vacation and she is on a wedding abroad atm. She used to pay for vacations, cook and was overall fun, although I caught her chatting with other guys.

Anyways, when she's gone, I used to ask her for keys so I can use her apartment to chill (good location, nice bath) and occasionally hook up with other girls, since it was conveniant.

Now I asked her for the keys 3-4 hours before she's gone and the apartment is all cleaned up, some of my stuff neatly arranged, all kinds of bathing salts with towels ready etc. So I get all soft and start emotionally investing more and basically not even caring about other plates and potential hookups. She should be back in a few days and I don't want to text more because I hate emotional investing into a girl I'm not fucking atm and she could be fucking someone else. Makes me feel like a cuck. And if I don't text at all now after already texting, she will see it as butthurt (I just know it). Is this apartment thing manipulation from her part and what would you do? I'm working towards another fwb and I kinda want to keep this one around on good terms, but I get possessive/jelaous when she is not around. I don't have ltr plans with her, but I want her to give her best.
