That he doesn't want to get married. Maybe. Gotta talk to him about it.
Jokes can be bad like horible jokes or they could be mean. Mean jokes can be funny, but don't over use them.
If you mean in the case of one of your parents re-marrying - the children of the new partner are your step-brother/sisters.
Telling jokes means to speak jokes through conversations, but playing jokes means to perform jokes practically.
They will always want something from you but never return back to you
If you mean 'marrying', Prince William is marrying Kate Middleton on April 29,2011
They're Just wasting your time get rid of them!
Yes. He always laugh at your jokes I mean, who wouldn't :)
Jokes On You
The common translation of 'bromas pesadas' is 'jokes'. But only a exaggerated form of jokes, like heavy jokes, pranks, sometimes even dangerous jokes. Most of the time these are also humiliating for the person that undergoes these pranks or jokes.
That would depend, if the jokes are mean spirited then he does not. If on the other hand the jokes are such that you both can laugh at them then he probably does like you. Further more the jokes are his (somewhat immature) way of getting your attention.
He/She liked you now
