Jessicate, thank you so much for your advice and also thanks to you, Bleeder.
Yesterday we spoke to eachother on the phone about going on a holiday together in the summer (with my parents and their friends, that means we will be the only two youngsters). He said that he absolutely liked to come, but it's not 100% sure yet because he'll be on a trip with his buddies before that and still doesn't know when he'll be back. So he has to find out. I asked him to be honest and he really said, ''yes, I do want to go with you all''. I hope he's telling the truth, cause if he lets me down I'll be alone on that trip
My other friends are ''poor students'' and also have other plans with their bfs and gfs. And my parents have to take leave from now on, so I have to decide and I don't want to go without my bestfriend.
I' ve made the decision not to call him again for sometime, because the last few times it was always me who called. Maybe I shouldn't show him that I miss him (which I do, even when I'm with other friends).
Please, if you have any new tips on how to ''treat'' him , please tell me!
I am so thankful to you all!
