So me and an acquaintance hooked up randomly just over a month ago and since then have started up a type of FWB thing. As time went on we started messaging each other every day and have hooked up with each other on more or less a weekly basis. Everything was going nicely, if we saw each other out we would end up going home together or we would schedule a day for one of us to go over to other persons place for some drinks and to hang out and chat before and after sex and sleepovers don't always happen but they have a few times.

However over the past week we both messaged each other all day with plans that we would see each other out later that evening which we did but when we did we flirted hard in front of mutual friends and almost got caught making out by a person that he has been on a few dates with (which we never used to be that obvious with flirting and pda before)

We messaged the next day that we shouldn't be as dangerous and haven't messaged as much since but we have hooked up again since this happened but I'm not sure what's changed, I'm not sure if I have feelings for him or if he has feelings for me but it feels like the dynamic has changed a little and I'm not sure what to do about it.
