I met this girl around a month ago and things were great. We had tons of similar hobbies, essentially the same personality, and got along really well. We went on our first date and it was super fun. I don't make first moves on dates, and I'm also not really a sexual person unless I have a romantic interest in someone, so the most we did was hug each other. We went on our second date where we made out and touched each other a bit, but nothing like full on happened. For the second date, she randomly asked me to come over during about 11pm, and I agreed but said that I would take a bit to get ready because it was pretty out of the blue. She then said nevermind because she had class in the morning and wouldn't want to be out too late, which I understand, but then she said to just come over anyways because she really wanted to see me. During this time we would text each other very often and occasionally call or facetime each other just to talk about our day. Then randomly, she just stopped texting me as much. It's not that she isn't talking to me at all, because she still does, but I'll be on delivered for almost 24 hours and then she'll text me really late at night and we might have a conversation then. It's weird because she's not being boring or acting uninterested, in fact, she will always say how much she misses me, compliment me, or talk about how much she likes me. We'll still have genuine conversations. Last week I asked her if she wanted to hangout during the weekend, to which she replied that she would be too busy, perfectly reasonable. Then, when she texted me back for the first time that day at around 10pm, she asked me to come over, which I agreed. I bought her some gifts and gave them to her, and she was very appreciate, she even gave me a gift too! We ended up hooking up that night, and a bit later I ended up leaving just because it was getting late and we both had to get up early in the morning. And then this weekend she ended up doing the same thing where she randomly says that she's free and for me to come over, to which I did, and we hooked up again and then I left not too long after because her roommate was coming back to her dorm. It's just strange. She seems so clearly interested in me whenever we hangout, constantly giving me compliments, cuddling with me, kissing me, staring into my eyes, blushing, smiling, laughing, all of it. But at the same time, I know that she is actively ignoring my messages. Well, maybe it's not intentional, but at the very least she isn't putting in the effort to do so. I say this because I will see her active on social media and sometimes making posts, yet I'll be on delivered still throughout that whole time. I don't know, it's just confusing. I'd love to talk to her about this, but we've only been hanging out for a month and she's not my girlfriend or anything yet, so I feel like that wouldn't be the best thing to bring up. I mean, I'm committed and loyal to her, but I haven't actually said that, so I don't know if she is to me. This could just be nothing, but she did have a bunch of condoms in her desk a few weeks ago, and this weekend she had none of the ones she did previously have, and only had a few from a different brand. Maybe she just gave them away to her friend or something, but just something I noticed. She actually hit me up first, and proposed the idea of us hanging out first. So, I know she likes me, and she clearly brings up and emphasizes how she does like me. She'll always say how much fun she had and how we need to hangout again, but then she just goes back to ignoring me. I understand that people get busy, but it's just the fact that I know for a fact that she will be texting other people and not texting me. I don't really mind, but I would at least appreciate some communication saying "Hey, I'll be busy today. I'll text you if I get the chance." or something along those lines. Once again, I'm fine if she isn't much of a texter, but the only reason I'm concerned is because we texted practically every second of the day at the beginning of us hanging out, and then that just vanished. Any help or advice would be appreciated. I would love a relationship, but I asked her what her dating goals were around when we met and she said that she wasn't sure if she would be ready for a relationship now (not with me, but like just in general), I said I understand and that I was looking for a long term relationship, but am completely fine with what she wants.

TLDR: Met girl, went on a few days, talked all the time. Then she went to only texting me once or twice (if lucky) a day and asking me to come over, have sex, and then I leave. I feel like I'm just being used for sex, but the things she says to me on text and in person make me think otherwise.
