just an opinion here; but i was in a very similar vanilla relationship, and she's not taking you seriously. you as in the two of you.

the girl i was 'with' (oh the bitterness lol) turned out to be married. and pregnant. and during one long pause in communication she moved four states away.

the internet and phones are great, man, but the only way to know you have time invested in something real is to be able to touch/see/hear/taste/smell it.

best of luck
