What to do?

I haven't saw my BF in two weeks because I was making out with him like that...and my parents saw it...so they won't let me see him right now but I believe they set me up they told us to go outside for some privacy one night and they stars were out and the weather was just right but when I tried to open the door to go back in I was locked out and they wouldn't open the door so when they finally opened the door we were sitting like that picture and now they don't trust me can someone please help!!
