Putting 99.9% into the relationship...

OK my SO doesn't hardly buy any house hold items, food, chip in on the bills, nor helps with house work!!! All he wants to do is be lazy and play games on his phone! Well last night I'd asked him to pick me up a pack of cigarettes on his way home! He handed them to me and I went on about my business! An hour later he holds his hand out and says are you not gonna pay me back for your cigarettes?? I was hurt as I pay for everything!! Should I feel upset or am I over thinking it!! Thanks ladies!!!!
