Give her surprise gifts at times (gifts that are useful in her life). Be a good listener who listens to her complaints and grumbles , comment them when needed. Try to match her interest too. I think the main thing is to let her know that you will be there for her. I hope she do that for you too.
*Treat her as though you only have eyes for her, even if you look at other women, she doesn't need to know. *Tell her daily that she's sexy & pursue s3x as often as you can, she wants to be wanted. *Don't abuse her, or call her derogatory names, never intimidate her or be aggressive, don't try to control her through dominance. *Give her freedom. *Be a man of honor, be trustworthy & a great leader. LOL, did I leave anything out?
