Too Committed?

I need some advice because everyone in my inner circle is kind of annoying me about this to the point where I want to cry lol.

So basically I met this guy. Right now, we’re long distance until he comes back to my home state which is about 3-4 months from now. He left about a month ago ago, and since he’s been gone, we text like everyday. He’s very attentive when we talk. I’ll send him a message and he’ll usually respond within ten minutes. Always telling me what he’s up to or his plans etc. Plus he plays a sport (not professionally just club) so he’s typically busy with practices and competitions. And if it’s not that, it’s school and homework. But even then, he still is always finding a way to reach out to me. And many times, he reaches out to me first not the other way around. He says he likes me (not sure what his definition of this is) and everyday I’m starting to like him more but we have no title.

Well recently, new guys or old “love interests” of mine have been trying to reach out to me, and I just haven’t been interested. I just feel like if I were to go out on a date with them or entertain them, I’ll just start thinking about the guy I’ve been talking to that I’m starting to have feelings for. And I just wouldn’t feel right. But I talked to my mom and my friends about this, and they’re telling me not to put all my eggs in one basket especially since the guy I’m talking to is so far away and I don’t know if he’s entertaining others too (though I highly doubt he is). They think I should entertain other guys if I’m somewhat interested in them. Am I wrong for feeling the way I feel? Or am I being stupid by being too committed to someone I’m not even dating yet? Idk I’m just super frustrated. Please help :(
