I've been through this kind of thing again & again. You make a date and then when it's time for the date the excuses come.
Don't accept his crumbs - you are being used. You can certainly do better. Here are two phrases I've used to help me decide if a guy was truly interested in me...
"He's not that into you." Yes, it a book title. Never read the book, but if a guy is really interested in you he'd make sure you knew it.
"Wild horses wouldn't be able to drag him away." A guy who is truly interested wouldn't be pulled away from you by his friends or anything else.
He's obviously "not that into you" and he's dragged away by his friends. Go find someone else who will give you the attention you deserve and treat you properly.
A few years ago I decided to not accept crumbs & I now have a wonderful fiance who tells his friends that he's on a long distance phone call (the phone call costs nothing to either of us) with his fiancee when they call & we are on the phone. LOL He's putting me before his friends. Also, I don't have to demand any attention from him - something you shouldn't have to do, your man should want to give you attention not be forced into it
