So I started dating this 18 year old about 4 months ago. Since then I've gone down on her a bunch of times and she has returned the favor (half assedly) about 3-4 times. She hasn't finished me once. I'm her first BF who she went down on / blah blah blah. She's not as intimate as I would like her to be. She says stuff like "we arent having sex" and flip flops a few weeks later and says stuff like "if we are going to do this, you need to be tested". i haven't been asking or pressuring her into sex. i just stay silent when she talks about it. fast forward to present, a few days ago she flew back up to her home for winter break (about 3 weeks) which is 300~ or so miles from me. The night before she leaves we end up making out and It's going well and passionately (atleast I assumed). Feeling excited, I went down on her, then she selfishly went to sleep without even so much as an HJ. I'm pretty annoyed with that but didn't show it. She said texts me today "Havent heard from you a while"

"You ok?"

She went as far to ask my friends if I was okay, one of them saying "Shes worried about you, text her!" and "You dead man?".

two hours later i say "Yeah" "Sup" then she says "Where you been" I assume this is a shit test / her attempt to keep tabs on me, so I ignore. She says "wantsdatp?" (my name) I ignore. She says "did I do something to upset you" I ignore again. I've told her intimacy is a very important part of a relationship a few weeks ago, so It's not like I haven't been communicating. What do I do? Ignore her for 3 weeks? Text her back every few days or so? This has been very frustrating. But she's gorgeous and fun to be around, just immature. Thanks for reading all this. I'm not really up to speed on how I should approach this given she's a virgin / I'm her first BJ / w/e else. she seems to think attempting to hold sex over my head will get her somewhere. besides that i do like her. just need an outside opinion on how you all would approach this.
