Talking to two guys (advice) Update

So I starting talking to someone I met on Bumble for about a month now since early December. We'll call him 'C'. He was around the area I live in temporarily so we didn't get to meet but we've kept good contact and we've really started to like each other. We just haven't video chatted yet since we've both been busy, especially him. But we've been talking on snap so we send pics and videos sometimes back and forth. He's so incredibly kind and always makes me smile. He makes me feel beautiful even though we haven't even met. Around the time it marked a month, I guess I started to realize how much I was starting to like him and I freaked out. I've made the mistake of putting all my time and energy on one person only to get hurt. And a few times it was long distance. So I figured I'd get back on Bumble and maybe I'd find someone closer to me. But that thought alone made me feel so bad. But anyway I got on and I met someone about 45 min away and in the army. So he's only in the area for about 9 months. I found all this out as we started talking. And we've been talking for about a week and plan on meeting on Sunday. We'll also call him 'B'. Y'all may be wondering what the problem is lol I don't have much experience in dating. I haven't really done much of it except once over the summer and with one person. No one since then. So talking to two people at once makes me feel like I'm cheating 😂 Which is ridiculous because I'm not exclusive with either of them. But with 'C' idk it feels different. I don't wanna stop talking to him. But I don't know how to tell him I'm talking to someone else, if I should even tell him. Because it may not work out with B. I mean the other day C sent a pic and I commented how incredibly handsome he is and he replied with and "I'm all yours" and I said something like "Aww 😊So what does that mean though? I mean that makes me so happy for you to say that. But what are we exactly? Lol I've been wondering this for quite a bit. 😊" And he said "I really really do like you!! That for certain. And I 100% wanna keep in contact with you. But I definitely wanna get on a couple video chats before putting a permanent label on anything, if that makes sense!" And I said how it made perfect sense and he said something later like "I'm telling you now though, if things go well I'm wifing you up". It's things like that that make me feel guilty for talking to someone else. What do y'all think? How should I bring it up to C if I should? Without hurting him and having him realize that my feelings have not changed for him. And I know I should maybe let B know when we meet that he's not the only one I'm talking to but at the same time I don't think I should, unless it starts to progress. If y'all have stayed reading this, thank you lol I'm sorry with how long this is. I'm just a little lost and confused here.

* Also some of you may have seen my post of me basically ranting about this other guy I was talking to. And how he wanted to sext and I obviously didn't want to, yea we don't talk anymore 😂 Just wanted to update some of y'all on that.*

*Update* 1/18

Going on a date with B tomorrow. Hopefully it goes well lol I'm nervous 😅 I haven't been on a date in a very long time.
