Am I to blame?😁

Kay🔥😈
So the other night I stayed with a friend and she usually has a lot of guys over and I recently got my heart broken by the guy I had been dating for 2 years and trying to get back out there and find someone that I like. I wanted to get to know this guy we will call him H. Well H is friends with my brother but is my age and I knew him and knew he was a good guy so I stared talking to him and well he ended up going home and so there was this other guy ( call he L)I didn't really like him or anything but I basically said what the hell so we got ready to chill out at the house and around there I'm known for my back rubs and this other guy was like give me a back rub and I did but L wanted one too so I gave him one and he said that he wanted to give me one so I took off my shirt and he started to rub my back. To skip to the good stuff we ended up making out and that other guy sat up we thought he was just asleep cause he didn't saying anything and he would have so we just blew it off. And well we made out for a good 3 hours and just talked in between. It got my mind off things. Well that morning I told my friend and she told me that he had a girlfriend. This shocked me cause he kissed me first and I had no idea. Well I was like okay don't tell anyone she said yes so I blew it off and just went in with life. Well 2 days later Ls girlfriends  sisters boyfriend -which is one of my long time friends asked me what happend and I was like you with her he said no so I told him. And j knew that she knewn. And well the word got around and now all of out mutual friends are saying it's my fought of what happens and I don't think it is. Am I at fought? Still panicking! Help!?!?
