Find her something to do for a couple of hours a week while you get garage time. It could be something simple like seeing a movie with some of her friends or getting a drink with some co-workers. Then have a day for just the two of you, and put a little effort into it (plan something). Lastly, if you have difficulty finding the time to do the things you want/need to, don't have any children. Your "free time"to will vanish and your priorities will change. I love my kids, but between work, school, sports and wife I have no free time.
P.S. Most of us don't mind the F bomb you dropped, but there are minors on here and it is against the forum rules. Try to edit that out with some $#%& so that you don't get a mini-vacation.
