Dp and I have 2 friends who are getting married very soon. It's been a bit of a whirlwind romance so the whole thing is being done very quickly and on a small budget. All fine.
The wedding is on a weekday morning, with a reception in the evening, meaning Dp and I have to take a whole day off to attend. We don't have to take annual leave but do have to swap days around with colleagues to make it work, especially due to the short notice.
Dp asked if we were going and I said I didn't know because we hadn't been 'officially' invited by either of them - not just no paper invite, (which is fair enough as they are on a budget) but neither of them have even bothered to get in touch directly to ask us. We found out the details (time, etc) and that we are indeed invited, through another friend who is also going.
Aibu to think that if they can't be arsed to even text/phone/fb us to ask us to come they can't be that fussed if we aren't there? I'm just wondering if it's worth going to the effort - I do like to make an effort with these things and would have bought a nice card/gift but I'm really short on money at the moment and the thought of spending what little I have on someone who didn't even make an effort to invite me is irking me a bit. It feels a bit rude to turn up with nothing 
Aibu?
