So he thinks im using him ...?

Ok so im friends with this kid (were both 15 year old dudes) and we had some little dumb fight a month or so ago over stupid bs like me saying stuff behind his back and other just pointless stuff.. And before we had this fight i was angry with him one day so i made a sick joke to my other friends saying like "we should atleast stay with him until the summer so we can use his pool". And a few months prior to that i apparently made a remark along the lines of, "lets see if the palace is open" when we were looking for a place to sleepover. He has a VERY nice house, hence "the palace". Anyway, were friends again but he thinks im just using him for his nice ****, mainly his pool. Although this is not the case, he is "testing" me by not letting me use it this summer. Which seems reasonable...if i was actually using him. He is my best friend and I would NEVER use him or any of my other best friends. Me and him hang out constantly with these 2 other guys and were all just really tight and have been for like 2 yrs. This just bugs me becuase im not using him, i never would, and i'm still gonna be letting him stay over my house, and giving him rides to go kart and do other fun stuff like that , and hes not gonna let me anywhere near his pool. thats not even whats getting me so upset tho. Mainly its the fact that someone i think very highly of and would never use thinks i am using him and is making it very hard to be his friend. I dont wanna put up with this stupid girly drama , i have alot of family stuff going on at the same time. What can i do to try and make him look past these 2 remarks and see that im not actually using him? im nott going to miss out on a whole summer of fun **** at his house with my 3 best friends but have him do everything that i host. Thats not fair to me. I have 4 other pools i can go in just as often as his, this is ridiculous. Please help, i really dont wanna have this friendship end because of something dumb like this. Thanks
