I can't tell you how to cope as a woman as I can only give a guy's perspective, but there are obvious similarities I guess. My first question to you would be, why do you want to cope with loneliness in marriage? Like, why stay in that marriage if you're just going to be lonely. And there are levels of loneliness as well. Where are you at with it all. I'm lonely in my marriage, but I've got thru different levels and settled into a lifestyle that suits me for now (although I still lack some things). I guess for me, the way I cope if by keeping busy and distracted by other things; exercise, hobbies, camping, reading, music, a couple friends.
