Does my best friend have feelings for me?

Okk I posted a question about 4 months ago about my best friend and I..take a look at the question if you want any prior details. So about 2 months after my best friend accidentally kissed me at a sleepover, we had another sleepover. This time we were fully awake and kissed like 6 or 7 times. Afterwards we dropped the f bomb a good 10 times and almost drove ourselves insane because of what had just happened. We talked about it later that day when I got home and we decided that it didn't feel wrong but there were no feelings there so we were gonna continue to do it for fun. All that happened for the next two months were random occasional hookups. On the first day in April, we happened to have another sleepover and we ended up feeling each other up and one another. We swore after that day we were done with all of it. That lasted for about a week then one day in my car we kissed again. That weekend we happened to have a tournament together and sleeping together that night led to us doing everything including eating each other out. Throughout these months both of us had been confused about our feelings but we had rules: #1 if one of us felt something we'd immediately stop and #2 this couldn't happen while we were talking to guys (both of us are interested in boys). We talked about doing it again after that tournament night and she told me she couldn't wait. A few days ago she started talking to a really cute guy but yesterday she came over and i knew the rules so I didn't even touch her. She ended up kissing me and other stuff happened right there in my bed. Half way through she stopped kissing me and said I'm talking to someone and I was like you're right let's stop she told me she didn't care and started to kiss me again. It was amazing and I'm 99% sure about my feelings at this point and I think I'm in love with her. But last night she went out with her guy and she texted me saying she had a great time and she really thinks she likes him.
