Please ask your GP to swab your baby's mouth for thrush, just in case that's preventing healing.
I recommend also using water therapy - hot bath or shower and take your time; it's therapeutic and will save you in many ways, even if it doesn't 'save water'!! Spend time in the bath just massaging milk out of your dodgy breast after expressing.
The money you spend on an LC (an IBCLC qualified one, not just a hospital title conferred on a nurse who doesn't have this international qualification - Kelly has posted the LC finder for areas in Australia) will save you money on formula, medical bills and the hassle of keeping formula equipment stringently sterilised (the way formula is made makes it very susceptible to bacterial growth, hence all the sterilising that goes with formula feeding). Think about it - $100 for the consultation of someone for whom boobs are their business compared to the regular purchase of formula over 12 months!
You're doing great.
As for DH, there are PLENTY of ways he can be involved in your baby's care that don't involve feeding - there are nappy changes, baths, taking bubs for a walk in the sling after a feed (the satisfaction men feel when a baby falls asleep on their chests in slings is lovely to see!). Right now, evolutionarily speaking, baby needs only you for all her biological and psychological wellbeing. A lot of men take this as an affront and some accept that their time will come - and it DOES! At about 4 months when the baby becomes a lot more interactive you see the change in their relationship. It's OK if dads don't feed babies, so there's no need to force or accelerate the issue
Definitely give ABA a call, too - great chicks on the other end of the phone!
