Should I buy a new baby gift?

[ToMeToYouAndBack]

Partners nephew and GF is expecting first baby tomorrow (c section) and partner asked if I would pick a present up for them. Now, his nephew doesn't speak to me, he patently ignores me in group family settings. Nothing has ever happened between us, but he just doesn't speak to me. I don't really know his girlfriend either. AIBU in not wanting to buy a present for them when they are just so rude - and I have made the effort to speak to them. It's like the whole family on his side thinks they are an exclusive club that no one else can join.

Something passive aggressive?

Haven't really seen pregnant partner, so not had a chance to make a bond with her.
Baby is here now and healthy so all good. I don't wish any bad on anyone but I'm not going to bother with anyone who cannot even speak to me or my partner unless they want him to do something for them 🤷🏻. Partner has ordered and sent an Amazon voucher when I said I didn't have time to shop, so all good

You're not doing anything for the nephew, you're doing it for your DH!

Tell him to do his own shopping?

Lazy fecker!

He was busy, but all done now

glad to hear DH ordered and sent a voucher. In general, you shouldn’t feel obligated to spent your time and effort buying presents for someone that is dismissive of or rude to you. It’s DH’s family he can buy all the gifts.
im in a similar situation with my in-laws. They don’t acknowledge my existence, yet it was me who remembered and organised their gifts for all occasions. I stopped getting the gifts for nieces/ nephews as I found it too upsetting and why should I invest thought and effort in them when it’s not reciprocated? Instead I spend the time on myself. It’s a shame as DH is rubbish at gift buying, especially for the nieces, and I enjoyed picking things they would like.
