Secret meetings with an unrelated male, even if it be to 'discuss islam' , are highly frowned upon by Islam.
If you two really want to be together, pl talk to your parents about a possible Nikah/Marriage in the near future. And really contemplate upon the issue.
If you both wish to discuss any future chances at marriage, it should not be done so during secret meetings, but in the presence of your guardians/parents. . .
Its probably just an infatuation or a crush, so try and deal with it, rather than furthur contemplate things by secret rendezvous. . . Also, just a word of caution sister, even though it is JUST AS wrong for the male in question to have a romantic affair out of wedlock, often, females are the ones that society frowns upon . . . hence I would urge you out of sincerity to watch your back, and keep in mind that there is a huge possibility that the boy's parents will not like you.
Sorry to be so blunt, but I did not want to beat around the bush. I would not even reccommend having 'friends' around and confiding in them, friends often aggravate the issue and gossip, and may not have your best interests at heart. Also, rather than acting as your conscience, they will probably tell you its okay, and part of bieng a teen, and that love conquers all etc. . . .
I also want to point out, that in such romances, unfortunately girls are the ones that usually go through the most emotions and heartbreaks. . . so please dont take that path. Because get real, at 17, do you really see yourself married to him at 50? It will all blow over within an year or two. And a romantic relationship, that does not have the possibility to blossom into something stable i.e. marriage, is a useless and trivial pursuit. If not you, it will be your beloved that will want to part ways.
The best advice I can tell you is to pray to Allah and try and be practical about things, I know its a hard age, and a hard time. . . but with Allah's help you found the Truth, insha'allah you will pull through this one as well. Be strong.
"O Lord, forgive me, my parents and Muslims in the Hereafter. O Lord, show mercy on them as they showed mercy to me when I was young."
