Re: tell the hand!
I wasn't going to post a reply but reading Mizz.Yasmine's post, I think someone is sharing the same opinion with me.
It's kinda unrealistic to a certain extent IMO. You guys are only 19 and still have a long way to go with education, career, and all that stuff. Being so very far away from each other, never having spent time together before (I'm talking about like people spending time abroad and running into each other, falling in love, that kind of thing if you know what I mean), and being so young, I just don't think there is a big chance of the relationship working. Please, don't be offended because I just want to be frank about what I think is best for you. You two are very young so there are so many options in life for you two.
I'm too in a long distance relationship but to me there is hope for our future. We're both from the same country, same city, had spent time with each other before going far away, and we both are in the U.S. and in the same time zone. We have the same career path that we want to follow.
BUUUUUUT, he already arranged his trip, so you should enjoy the time with him and then consider this while and after he's with you. I wish you the best!
