i don’t know how i feel about my boyfriend…

me (16F) and my boyfriend (16M) have been together almost two months. i’m really just confused about my emotions regarding him because every little thing he does makes me SO annoyed. he scratches his skin constantly because he has eczema and every time he does i get so ticked off. every time i walk with him (kinda harsh im sorry) i feel like a lost puppy is following me. i don’t know why but when people walk behind me and i’m walking in front of them, like basically WALKING them, i get so annoyed like walk with some pep in your step! he also just breathes really loud and chews with his mouth open. i also don’t really find myself much physically attracted to him anymore just because of all these irks… he’s so super nice to me and im also his first gf so i just feel this burden on my shoulders IDK WHAT TO DO
