in need of help

Lea

my partner and i have been together for a little over a year now. we live in separate countries, so all of our communication has to happen over twitter or other social medias. i’m a teenager, so i don’t even know what love is or what i’m feeling but i do know that i care about them a lot. but there are these periods of time when they just disappear. i can’t get in contact with them, they won’t answer me, they’re not updating anything sometimes for a month or two at a time. them being gone for so long so often makes me question myself, and then question my feelings for them even further. they never tell me what they’re doing for those weeks, just that they’re busy and that they miss me. it’s getting to the point where i’m not just missing them i’m having breakdowns because i’m trying to figure out who i am and because this person is gone for so long i can’t connect with them on an emotional level so that just makes it more difficult because i don’t know what i’m feeling. i don’t want to hurt them but i don’t want to have to wait around for them all the time. i’m just not sure what to do. help?
