He still care and mind..

this is what i realize.. my guy always say he don care, he don mind.. actually he do..
after clubbing session on Halloween night, he react different.. he have nightmares, which usually happens to me only.. he dream that i left him for another guy.. yesterday, he saw the pics that i took with colin and tien when clubbing and asked.. is his hand over ur shoulder, i replied.. yes.. feeling abit awkward.. feeling guilty too.. but is like nowadays, friends do that all the time.. *correct me if i am wrong* friendly gesture.. is that common now?? i can't be like telling the person "pls get ur hands off my shoulder".. it will make the situation wierd... but i know that when my bf see that, he will feel uneasy and if i were him.. i will too.. who will like to see their gf or bf so friendly with others right??!! after that night of clubbing, i kinda like it *honestly*.. is like i am starting to explore things that i never get to do it when i am younger... on the other hand, i feel very guilty.. he wont tell me not to go, he wont say i cannot go, he wont stop me from going.. but i know deep down, he mind alot.. he started to feel unsecure.. and it kinda hurts me to see that i make him have this kinda feeling.. that was not i intended... although somtimes i would like him to feel that i am important.. but not to this kinda extend.. i am not gonna make any promise to him that i wont go clubbing with my friends as i am not sure whether i will or not.. just dont want to give him any empty promises.. i am going through a stage that i am not sure how to react too.. is like i like to do this thing.. on the other point, i dont want him to feel unsecure.. dilemma..
