Idk,
control issue perhaps but then why would I be happy when he goes out with a bud? Only thing I appreciate is be told his schedule (ie when he is planning to go and it not be just out of the blue then be going).
Possessive perhaps, he is the first person I have allowed myself to be with in a relationship and don't want to lose him. He is the first to seem like he actually likes me....

sigh, Idk.
