-nc but a regular. I will set background out but not say which party I am for now-
Background
A & B have a child, C, who is 2.
A works fulltime Mon-Fri. As such A does not have a day/time without C, unless A is at work.
B works a 4 week rota, working 5 days out of 7. Fortnight 1 is Mon-Fri with Sat/Sun off, Fortnight 2 is Mon off, working through Tues - Thurs Fri Off, weekend in. B has C on the Mondays B has off but has the Fridays to theirself.
A often buys items for C - small toys such as cooking set when on offer for £1.66 for example. A also has the joint bank card. B has one too but never carries or uses it. As such A uses the joint card for items such as shopping, or top up shops that are going to be costly - i.e. £5 or more (If £5 or less, A pays out of their own pocket). B often does the same but as A is often travelling home from work without C, it's easier for C to get the items needed. A's parents don't live far from the family and A's mother bits lots of bits for C (toys from chariety shops, tshirts etc). When the family go out, they go out in Bs car. No mention is ever made regarding fuel spends.
C's birthday is approaching. C will be 2. A and B have a giftcard for Argos so decided to buy an expensive gift for C. A feels that because the giftcard was "free" that it does no harm to spend the full amount. B says it it just spending for the sake of it and it opens a can of worms. B says they feel A is always buying things for C and B never gets chance to do so as A and A's parents are usually the buyers. B feels put out and cross because of this. B brings up the fact that when B has bought things for C, this has been out of B's own money and not joint funds. A explains that they also buy items out of their own money - taking shopping and small token gifts explained above - so it's equal. B then throws into the mix the fuel money spent out of their own pocket to which A says it's not a competition.
So, if you've followed all of that above... Who IBU:
in regarding the gift card - ie spend it all or not
in regards to small token gifts
in regards to joint/separate money.
