AITA for asking my friend to repay me for breaking my lamp?

one of the guys that i (f21) live with, who i’ll call B (m20), has been noticeably colder towards me than he is towards our other housemates. i never really understood why, and one of the girls said she’d picked up on a ‘weird bad tension’ between us. when i spoke to her and another housemate (both closest to B), they both attributed it to the ‘lamp incident’.

this happened last november. we’d thrown a house party and B had his laptop and his friend’s dj decks (which he was borrowing) on the kitchen counter. at some point in the night i drunkenly knocked over a glass of wine that was on the counter, which spilled onto the surface and the laptop + decks. i immediately apologised profusely and cleaned it up. thankfully, the decks were moved quickly enough to avoid most of it. when it briefly seemed like B’s laptop wasn’t turning on, i apologised again and asked how i could remedy it, including paying for repairs (even though i wasn’t in a great financial position). however, in the end both the laptop and decks were completely unharmed.

for the party, i’d given up my favourite lamp from my bedroom to use in the kitchen. a couple of hours after my spillage, B drunkenly knocked it over and it completely broke. i was upset, but he apologised and said he’d pay for a new one, so i let it go. the next day i bought a replacement and messaged him asking for £10. it had cost £13, but i remembered i owed him £3, so i told him i’d subtracted that from what he owed me.

it then took about a week of politely asking for him to actually send anything. he left my messages on delivered and brushed off my few attempts to mention it in person. when he finally paid, he only sent £7. at that point i was quite broke and frustrated at how much effort it took for me only to get the wrong amount. i thanked him and politely clarified that i’d already deducted the £3 i owed him, then apologised and acknowledged it might seem petty to ask for £3, but i genuinely needed it at the time. he never sent the rest, but i dropped it because i was tired of chasing and he seemed irritated.

i kinda just forgot this happened until today, when i found out B had apparently been holding a grudge since then because he thought it was rude of me to ask for money for a new lamp after spilling wine onto his laptop/friend’s decks. i understand the situation was stressful, but i didn’t end up damaging anything. he completely broke my lamp, which was a lot less expensive but still something i valued. apparently he only offered to pay as a courtesy and expected me to let it go because of my earlier mistake. in his words, it was the ‘principle’ of it.

i’m just annoyed that something so small and petty made things tense between us for months. it could’ve been easily resolved, and i also don’t think i’m necessarily in the wrong for asking him to pay me back. i understand his initial annoyance and stress, but this feels unfair to me. AITA for asking him to repay me after my fuck up?
