ESH you let him get the chikens in the first place, he did not know your dog would do harm to them however he is an asshole for not making a space for them because it is your house, u are an asshole for even thinking to break up over this u dont value your relationship nearly enough. i know im not allowed to say my opinion BUT(pewdipie Gloria borger refrence)hell u have been living with chikens havent u, u are not supposed to be thinking of them as his chikens or your dog they are our pets not my Pet And your Pet thats so wrong my heart aches some People make me sad, well if that was me i would Just tell my girlfriend to take time off And do it together And have fun While doing it, like if you are lazy And Just dont want to do it cause its his problem to deal with, u dont love him nearly enough like i love my girlfriend :))
