Every time I ask my boyfriend if he wants to go do anything, he can't?

I asked my boyfriend if he wanted to go ice skating with me and some of my friends he said his grandma's birthday was that weekend. Then I asked him if he wanted to go to the mall with me and some friends and he told me maybe, he said he might be a little late but then when I asked him what time he was coming he said he couldn't cuz his dad wasn't home. Then I asked him if he wanted to go see a movie this weekend with me and some friends and he said he couldn't cuz his dad gets off all weekend for the first time in a long time cuz it's the 4 of July Monday. ...... Do you guys think he's making up excuses or really can't go. Cuz he can never go do anything!
