Input: So for a bit of backstory, I have a friend, let's call her D, who I have known since high school. We used to be quite close but haven't really spoke recently due to D making some extremely rude comments to both my girlfriend and sister (We're all from the same hometown) around 6 months ago.

Anyway Me and D go to the same university and when we were friends I introduced her to my housemates who she is now friends with. D decided to have a last minute party last saturday which my house was invited to. I against my better judgement decided to let go of the past and attend.

On Saturday morning one housemate posted on our group chat that he was going to the shops to buy D's birthday present, which I thought nothing of. I was out of town on Saturday morning but arrived back on Saturday evening. When I arrived back the housemate said he'd gotten a card for D from the house, which they had all signed and to sign it too.

Anyway the party was a bit of a disaster, with D making numerous snide comments about my girlfriend which very nearly made me leave.

Anyway the next day my housemate messaged the group chat asking for $30 each for D's present and card. I was quite shocked and messaged back refusing to pay, given that at no point had I agreed to a joint present ( I don't even know what he bought) and that as a broke college student I would not have agreed to spend that much. If me and D were getting along i probably would just let it slide but no way was I paying $30 on a present for her. His argument was that I signed the card and didn't say anything on the group beforehand when he said he was getting D's present.

So Reddit AITA for refusing to pay?
