WDID if I meet another guy while I have a long distance boyfriend? (**ADVICE DESPERATELY NEEDED**)

Hello fellow potatoes. I’ve been stewing with this situation for a few days and I genuinely don’t know what to do and could really use the help. It’s a really tough situation and was hoping yall could help a girl out. (Throwaway because I don’t have an actual reddit account)

I (F, junior in hs) have been dating my long distance boyfriend, who we’ll call “Tommy”(M, senior in hs) for a few months now. For context, his mom is a nightmare who grounds him for being independent and takes all his devices, so we rarely get to talk. Maybe once every few months for about half an hour. So far, in the conversations we have had it has been good, we talk about things we’ve been up to, school, stuff going on at home, etc.. During all of this I’m getting a follow requests on Instagram from the same person (this is important) who we’ll call “Billy” (M, senior in hs). I’ve declined them every time cause I didn’t know who he was. A few days ago, I see the follow request from Billy again, and I decide to see what he wants since we have a few mutual friends on Instagram. I accept the follow request and I follow him back. TLDR; We used to go to the same school and he noticed me around the performance arts building at our school because we both had different classes in that building. He said he wanted to get to know me so I gave him my number cause I’m never on Instagram.

I’ve been talking to Billy for a few days now and he has started flirting with me, and it dawns on me what’s really going on. Meanwhile, I haven’t talked to Tommy since July (about a month ago). I really care about my long distance boyfriend (Tommy), but long distance relationships have never really worked for me as I’m a very clingy touchy feely person. It’s how I show my affection (hugs, kisses, cuddling, etc.). I do think Billy is attractive, but I’ve never been someone to cheat on my partner, I’m just not that kind of person, but now I’m rethinking everything about who I am morally. (For anyone who might be curious, I’ve never made advances towards Billy, and always give him vague responses)

For more context, my home life isn’t that great either, my mom would be one of the evil narcissistic MIL’s. I’m very much an overthinker and overexplainer unintentionally and I’m very prone to feeling lonely even when I’m with my closest friends. I would really love some advice from the lovely potatoes who I feel like would never steer me wrong.

(Edit: I will update if I get responses and once I choose what to do 🙏)
