My (27m) girlfriend (23f) snapchats the same guy every day

I couldn’t help but notice that my girlfriend of three months is talking to the same guy each day. I know that this is a very new relationship but we (as far as I can tell) are very into each other and at least on my end I believe I may be starting to fall in love with her already. It is unusual for me to hit it off with a partner and it is a very nice feeling. Once in awhile she will be showing me something and his name pops up or I will just so happen to notice that he just sent her a snap.. It happens frequently enough that it is clear that they talk quite often.

His name is followed with a “😎🔥” as well in her snap contacts which messes with my head even more. What really set me to writing this post (I’ve never started a Reddit thread before) was when she received a call from him in the car while we were driving. She didn’t answer it but his name in her contacts was followed with “itos”.. This is often a term of endearment right?

I know it has not been long but I really like this girl and from what I can tell she really likes me as well. I haven’t confronted her about it and I’m just not sure if I should say anything since I have no actual evidence…

I’m wondering if I am out of bounds to bring it up to her. It is weighing on my mind more and more over time. Do I risk damaging our trust by confronting her or is this necessary to talk about?
