am i just overreacting ?

My boyfriend like to keep me in the dark about things and lie to me . today everyone was going to a park and i had no idea until this morning and everyone was telling me he was going , but he said he wasn't he told everyone he wasn't and told me to my face he wasn't .. but as soon as i had left , he went straight to the park and when i asked where he was because i was worried he said "going to the dry cleaners" then one of my friends had posted a video in his car and after i told my boyfriend how i felt about it him and everyone else is making me out to be the bad guy ..  is it okay for me to be furnished ? (keep in mind he does this all the time to me)
