Like Busty, my husband is definitely my best mate, and while I love spending time with him, i also love going to a girlfriend's house and having a cup of something, or to spend the day making art - beading, painting, sewing. He has stuff he loves to do as well. I love coming home from these separate outings with news as to what i've been up to - showing him things i've made, photos i've taken, and I love hearing about a piece of technology he's built, or whatever. We do a heap of stuff together - exercise, explore the city (he's new to my town, so i'm enjoying showing it off a little), and other things - he even comes clothes shopping with me and I go to strange computer-part places that are like the soup-nazi kitchens but with hard-drives

. In saying that there are just some things he likes that i'm not as keen about and vice versa. He, for instance, doesn't love making jewellry, and I don't particularly like building computers, so we also definitely have separate interests.
Really though, the world don't move to the beat of just one drum, etc.
To the OP - the guy needs a bit of slack cut - he's new to a city, so is rightly relying on his partner for some guidance and to show him around - working will ensure he meets new people, which will definitely help. If he's going to slack off and just mooch around her house and live vicariously through her - then that's bad news.
