Quick rundown of my current situation is basically that I've got this girl that I was plating and just seeing for sex for about 4 months, but recently have been seeing her more outside of the bedroom for the last 3 months or so. We don't necessarily go on "dates" but will accompany each other out to events, hikes, and things I would never do with a typical FWB. I've now grown pretty accustomed to seeing her friend group as she has mine. Things have been pretty great, but I've been pondering the long term implications of us seeing each other.

To this point, she knows that I see other women on a regular basis and while she initially tried to shit test me, I feel like I handled it fairly well in explaining that I'm not interested in settling down at this point in my life. With that being said, one of the shit tests that she had tried pulling on me was telling me that she had gone on a few dates with some other dude 3 months into seeing each other which I could really give a shit about, however I did tell her that if she was gonna see other dudes that she'd need to get tested regularly. We do use protection during sex, and I do get tested regularly. So far nothing has come up, but how much longer can this go on?

On one hand, I do like seeing the girl and she's by far one of the best fucks I've had in the last year, but as we all know not all good things last forever. I could never see myself making this girl a LTR, especially after knowing that she's gone on dates with other dudes, however I do enjoy her company. Knowing that the time we've spent together has increased significantly recently this is starting to feel like an open relationship. What are your thoughts on how I should continue to play this out? I could easily NEXT her or maybe "branch swing" onto the next fling, just want to be prepared for any possible shit storms that could be brewing as a consequence of seeing her more frequently.

Thanks for the advice.
