I have the same thoughts. My wife just moved out and my sons spent the night with her. I didn't really miss her, but I miss the boys. I talked to my boys on the phone this morning with tears in my eyes. I feel bad about the fact that miss my sons so much, but not my wife. m I just don't have the same feelings for my wife that I have for my sons. I love her, but she's caused so much turmoil and pain, that I'm ambivalent. I hate to say that, but it's how I feel.
Will I continue trying to bring the marriage and family back together? Yes I will! But, in process I'm going to have to fall deeply in love with my wife or it's not going to work.
I know it's frustrating for you, but I think it's normal to feel conflicted. I guess we all have to decide when to call it quits, but that fact that you posted your feelings probably means that you still want to trudge on and try to save the marriage.
