Lads: would you feel comfortable, letting your girlfriend treat YOU to dinner out?

Say, if, for argument's sake, you'd been together for about two and three quarter years as a couple, and you'd actually LIVED TOGETHER for just shy of two and a half years of them two and a quarter years? Only, as much as I love to treat my girlfriend to dinner out and whatnot, she does like to treat me an' all every now and again, and no matter how long I'm with a girl, I NEVER seem to feel comfortable, letting her pick up the bill, when we go out for dinner, 'cos I'M the bloke with the pair of bleedin' Joes, so, in MY mind, I oughta be paying for everything, (and taking me girlfriend away on expensive holidays and buying her shitloads of bloody expensive clothes and jewellery, to boot, even though my other half reckons that crap means bugger-all to her!) Other girls I've dated in the past have been quite happy to take, take, take, take, take, without giving a bloody thing back, and that's all I've ever known! I ain't used to girls treating ME, and frankly, I don't think I ever COULD get used to that! It ain't traditional, and therefore, it just don't seem right to me! Would you blokes feel comfortable letting your girlfriend pick up the bill, if you guys'd been together, (and living together), for as long as I've already said that me and my girlfriend have been? And what are your views on this, please? I'd really appreciate your angles on this one, please, guys. Much obliged! Peace and love! Be lucky! :)
