I [16m] was too pushy my second time hanging out with her [15f] but the relationship is still salvageable (?)

A month and a week or so ago me and a girl went to a party together (I got drunk, she got high) and I ended up going to her house for the night to smoke weed. Nothing crazy happened the first night but we cuddled a bunch and talked about secrets (she's super cool and I want to get to know her better), which was probably the best night of my life in hindsight.

The next Wednesday I went to her house for the night again and I brought some fireball to share. Also, between visits I sent some probably very cringey snapchats to her. Anyway, we ended up drinking and smoking a bit and I tried to kiss her (?... can't remember this part super well) and she went with it kind of and we continued talking or whatever. At this point I was kind of fucked up so I kid you not I pulled out a condom and said "oh what's this?" all nonchalantly. That went terribly as you could guess and then she said she wasn't in the mood. She said I could play with her tits but I felt bad and didn't.

Now before you think "wow you need to calm down" realize that you are correct and that I now realize that my expectations were wayyy too high for our second time hanging out. I texted her the next day apologizing for being pushy and she said that she still had fun and that we could hang out again. I then gave her my number so she could text me while I was on vacation and left for camp/the UK for a month.

Now, vacation and camp is basically over and she hasn't texted or talked to me once. Did I do something wrong? How can I initiate something like the first night again? Is the relationship even salvageable? Should I avoid the drugs this time and go for a real date?
