So I've had this girl from Uni who I started meeting during our extended group get togethers for partying and whatnot.We started to bump into each other on a weekly basis from there on. It had been a good 2-3 months till we actually started to talk and really connect on a deeper level. I used to stay back at her place and just have late night convos with her and her roommate (who is a bestie of mine) . Now, fast forward to the day when both her roomates had to leave the place for their vacay. I was gonna be departing a few days later myself. At this point, we knew quite alot about each other. And so here we are, seated on her sofa playing chill rom type songs. We keep chitchatting about all sorts of things and then suddenly she decides to lie down on my lap. My heart beat shot up big time when this happened and she noticed it placing her head on my chest. Fast forward a few min, i approach to kiss her to which she obliges . It gets intense by the minute and then I hit 2nd base. I kind of knew she's not going to be as cool going downstairs as she did mention previously that she's not someone for a fling or whatever but knowing female nature I still kept going. I didn't really attempt to go further down that night but the following days when I had an exchange with her over text where she seemed pretty firm about doing it with 'The one she sees a future with' and the fact that we had such little time on our hands(since I was leaving for good) . But the kissing still continued up until the last day. Now my question is, is she really fixated on having it with 'That guy' or is this some short of shit test. Why would she not resist the kissing but show resistance to anything more. If it is indeed a shit test,how do I handle it?

TIA
