Hi T., First I want to say sorry you feel the way you do. I've been there. Don't think because your kids are grown that if you leave your your husband that your kids will not be affected because they are grown. My best friend left her husband after her two kids were grown, and now they barley have anything to do with her. One of my oldest sisters left he husband/family she had 2 almost grown daughters and a 10 year old son whom she took with her, he kids didn't talk to her for 3 years. Wife's become unhappy in their marriages very easily, but what I told my sister, which didn't do any good is that you don't rectify your own unhappyness
by making someone else unhappy, that's selfish. You need to be open with your husband about how you feel, and why you feel that way. True love, the real thing doesn't die, we as humans give up, we stop nurturing the marriage, we stop putting into it the things we once did. "Love never fails" people do. You need to re discover why you feel in love with him in the first place, you need to spice up your intimacy, you need to do all the things you can do to put the fire back, trust me it's fun. my husband and I will have been married 29 years in June, but 16 years ago I told him I didn't love him anymore, the most hurtful words that ever came out of my mouth, our 3 kids were the main reason I stayed. Us working through it, set the greatest example for our children of strength and faithfulness, and perserverenace.
Had either one of us left, we would have robbed ourselves each other and our 3 children of what we have today. If you want tomorrow to be a better day in your marriage, then do something different today. Through a church my husband and I have went to many marriage classes and worksshops but together from other couples who have weathered the marital storms, not councelors, or shrinks, couple just like you and us. If you would like to talk further you can send me a personal message, or e-mail me at ____@____.com J. L.
