<human>: Reddit, I can't stop thinking about this and have no one I can rely on to give me perspective on this - so any feedback would be really helpful. I'll make this as brief as possible, so thanks in advance!

So I've been seeing this girl for just under two months now and we've got great chemistry have communicated our strong feelings for each other. We both attend the same college and lead busy lives so we only get a chance to see each other once a week. However, I feel that the past few weeks have been different as she doesn't communicate (text, instagram tags, etc.) with me as often as she used to. I figured this might just be because she's gotten busier with school and she does legitimately seem overwhelmed at times juggling two other jobs. 

The thing is, she has this project for her anthropology class with the topic being online dating. So she eventually got Tinder on her phone to investigate that. We've had a conversation about online dating where she expressed to me her beliefs that people should meet 'naturally' or spontaneously in person (which is how I met her). Anyways, I asked her about her project recently while I was driving her home from a music show and she said that this guy asked her for her Facebook and phone number - which she gave him. Then she immediately told me that she told the guy that she's "not looking for anything" and that he said he just wants to be friends with her (oh my naive sweetheart). I was on her Facebook one day and noticed that she had these guys she had recently added whom I presume are through Tinder (as they do not attend our college). 

This leads me to seeking out some objective opinions/thoughts on the matter from r/relationships. I'm a bit confused and have been trying to think of a way to approach her regarding it.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: GF is not communicating with me as often anymore and has a project involving Tinder but is adding guys on Facebook and has given out her number to one of them. What's a good way to approach her about this?
