He never gave the first girl his heart, so she's pissed and trying to deny him everything from her trust to the rum, but there's nothing she can really do to be on top of the situation anymore because she already gave him her heart. She's trying to deny him every little thing in order to make up for the fact that she's already given him the biggest thing and not gotten the same in return.

All he can do is offer his stick of gum. He can give her everything but what she wants, his love. He can't give himself completely emotionally.

The first girl is also probably pissed because she's friends with his new girl; that's why girl 1 has girl 2's picture in her apartment.

I agree with the part about being emotionally crippled. The first girl has given the guy her "emotional legs" by giving him her heart. The guy just can't return the same feelings. He seems to be incapable of doing it with anybody. Even though he's found a new girl, he won't ask for a lot "I never asked for your crutch" because he knows he can't give a lot "Don't ask for mine"

He's unable to fully give in to love or fully give love, and he's warning girl 2 not to expect too much. Girl2 was in an actual wheelchair that she needed, kind of like the guy who won't give up his "emotional wheelchair". He can't give up his "wheelchair" (his heart). This is how he relates to Girl2. She also couldn't give up hers.

BUT the song indicates growth. Just as Girl 2 moves on to only needing crutches, perhaps there's a chance that maybe the guy will have a little more emotional give than he had before, but never fully. After all, Girl 2 will eventually be able to walk without crutches (symbolizing how she will one day be able to give herself fully to the guy), but there's no clear indication that he will ever want to give up his heart (it's his permanent "crutch, and in the warning tone of the last two lines, it's pretty clear he's afraid of her losing her "emotional crutch" because then he'll get stuck in the same situation as in the first relationship)
