Do u think this is selfish?

y'day my boyfriend and his mate/work mates were on their way home from work and his mates stopped and got a mc donalds for him and his girlfriend, my boyfriend didnt have nay money on him at al so his mate just bought him a burger, when they got in they'd al eaten but i hadnt had anything. i no he didnt have money but i just thought u could of said to ur mate do u mind lending me a couple of quid til later i best get kerry (me) something too while we'r here but he didnt. i did say to him 'didnt feel like asking me if i wanted anything then no' he just said 'i didnt have any money jon bought it' then he said 'oh here we go in a stress again are we' which does put me in a stress. latley we keep having little probs like this come up and its not a huge issue but things like this do really get to me...if i do ever mention anything he just seems to think im moaning and going on. how would u feel if this was u would u? i just feel its a little selfish. im confused?
