BTW..I think that what you've given your wife over the years, unconditional love and that you'll always be there, is EXACTLY what she needs, she just doesn't know it..because she doesn't love herself unconditionally..so she doesn't really get that..if that makes sense
I just say that because I wouldn't want you to think that you being a loving, kind, unconditional person is something someone wouldn't want..because they should/would! (did that even make sense LOL?)
