family/ relationship drama

so last night was my sweet 16 my boy friend was there it was great. I kissed him a couple times but I had to make it quick because my mum was watching. not to mention that a family friend was asking me is I loved him right in front of my mum earlier that day. so he leaves and now he is upset today because he feels like I don't want to kiss him. like for an extended period of time. anyway. we had a fight, I'm insecure, he said he isn't in the mood and might never be. now he is saying that he doesn't want me doing things just for him, which I don't. anyway. I have really high barriers that I don't know how to take down anymore. :( idk what to do. I love him.... (please don't say I'm too young) TIA. ;)
