should I give up??

As

my daughter is ebf she's 2 1/2 months old and for the past three days she acts like she is starving I nurse and nurse and she doesn't seem full she will fall asleep at breast but wakes up screaming as soon as I put her down everyone is saying it could be her teething or clustering again I want to try an 2oz bottle of formula and see if that helps but my s/o is super against her having formula he wants her to have the "real" stuff but I'm exhausted and frustrated cause all my poor baby has done is cry when she's awake I just want her to stop crying is all I have zero problem with formula my first born had it after 4 1/2 months
