When I use to date (married now) and a girl said she wanted to spend less time together I did just that. If we didn't have anything planed a few days in advance I would go out with my friends. Then if she would call wanting to do something last minute I would tell her I had plans and I wasn't going to break them "my friends are my friend because I keep my word and I can't let them down" Always keep your eyes open for something new. You never know when you are going to find something new and better. In other words just go out and have fun, there is no use in sitting around your place bored. She will see you can have fun with out her and she will want to be apart of that.
