I need advice!

Hey ya’ll! so im kind of in a pickle right now and i dont know what to do. I am in a long distance relationship atm, we’ve been official for 2 months but we’ve been talking for nearly 7. Everything feels different now. the chemistry feels different, we arent talking as much, and i find myself having thoughts about ending things. I love this boy, and I care about him so much, but things just arent the same. It would break my heart to end things between us, but I also feel drained, and sometimes it feels like a task, and i know it shouldnt feel like that. I really need some advice because i have no idea what to do about this :(
