Hi.
ok, first thing, i have to let you in on a little secret. if a guy really wants a girl, no matter, whats happening, he will go to all lengths to persue her. So i would not buy his 'im too busy'. guys are never too busy for the girl they really wanna be with. Also, the fact that he told you that there is another girl he likes, is a his way of letting you know that he has no intentions of going out with you again. If a guy wants to get back with you, the last thing he is going to tell you is the other girls he likes! So im sorry to say that i really doubt that he wants to get back with you.
And secondly, your worrying so much about him being happy at the prom, well what about you! dont you come first! what will make you have a good time, who do you want to go with.
Now you want to know if he wants to go with you or someone else to the prom. well to me it sounds like he already tried to tell you that he wanted to bring someone else.See guys may not be the most clear and direct communicators, they are mostly dont have enough guts and drop hints here an there.So if you still want to go with him, then you need to talk to him and ask him if he wants to truely go with you. clear the air, cause i doubt your going to enjoy the night if your worried about whether he is really happy being there with you.So be open and honest about it. Talk to him and ask him to be honest. ask him if there is any chance he wants to get back with you after this 'hecti perios' ends and if he wants to go with you to the prom. communication is the key my friend.
Good luck.
Take care.
