Hey man,
About the whole long distance thing, my girlfriend of 4 years just broke up with me, the last 2 years were all long distance as I joined the Air Force and it made it difficult to sustain a relationship. To be quite honest, as much as I was in love with her, in the end, it just doesn't work, and if you did love her, you'd stay friends. It just doesn't ever pan out the way it should, and to really assert your dominance in the relationship, tell her straight up how you feel about her in your relationship. Honesty is the key to a healthy relationship bud
If you feel as if the relationship won't last much longer, be the man and break up with her first, it'll be much easier on you and she will come crawling back to you in due time, thus, asserting your dominance. Glad I could help!
