My husband travels a lot for his work. Though I know he cannot help it, sometimes I really feel lonely despite kids, work, and other things. How do I overcome this loneliness?

why don't you try and engage yourself in activities that you are interested in and that will keep you happy while you are on your own? also, if possible, make small getaway plans to go and meet your hubby. that way, you won't be away from him all the time, as well as will get the much-needed break.
