Eeeeep! Boys, boys, and a boyfriend! HELP!?

so I went to the beach today and my boyfriend couldn't come a whole bunch of ppl were there and so these 3 guys tht I kinda like were there and one of them (Jack) we went to the quiet side of the beach and we had such a good time together we were skipping rocks and talking for at least 40 mins... I had such a good time! And then I hung out with another guy (William) and on fb one of his status updates was my name with a little heart next to it! ahhh! but he's such a good friend so I hangout with him a lot anyways. And then another guy (Isaac) I kinda like him... and it was sooo weird cuz another couple tht I'm friends with were on the swings and me and Isaac were on the swings too! So the couple on the swings, the guy was pushing the girl and then I started to swing and then Isaac started to push me... it was unexpected, weird, but I enjoyed it, it was sweet:) So yeah... But then my boyfriend came and all 3 of those guys left and for some reason it was boring with him. :/ Idk what to do! I feel like everything I did was wrong and idk if I should even be with my boyfriend anymore for what I did and how I felt! Please help some how... It's so complicated! :/ thank you soooo much u guys! :)
