Some girls are high maintenance, some arn't.
Here's the problem with those that arent high maintenance, sometimes you guys can take that for granted. I cant tell you how many times I've heard a man say about me "Oh she's not your avaerage girl, she doesnt like flowers and perfume, and jewelery, and candles, and all that typical romantic stuff." Hello! News Flash, I think EVERY woman at least once, would like that generic typical romanitic stuff.
If she hasnt been high-maintence PLEASE dont take that for granted. I think Nos does make a good point. Make her feel special, how about YOU cooking a special meal for her. Or do something, that gives her advance notice and tell her you want to take her out on a "date". I think that's exciting when you've been in a relationship for a while. It's not just getting dressed to go out, it's planing for it. Then go out on a "date" and do everything you would have done on a first date. Show her alot of attention, hold her hand, dont look at other women, make her feel so special for the evening.
Listen to what she has to say too. Maybe she has mentioned a new book she really wants to pick up, or a CD or new movie coming to DVD. Maybe her slippers are wearing out and she's mentioned needing new ones. Pay attention to that stuff. Sure women dont always come right out and say what they want, but we sure do drop an awful lot of hints. Then one day before you come home, just pick it up for her. That kind of stuff makes a woman feel special.
p.s. I like Nos pillow fight idea as well.......... nothing says luvin for me like being smacked in the head with a giant pillow.... no seriously :)
