Daily: invite her to spend time with you. Engage in conversation.
Daily: work on meeting some of the other emotional needs. Express affection. Provide DS or FC or FS or whatever she wants. Sounds like she wants O&H!

Weekly: communicate your need for SF to her. Communicate with her about her love busters (use the worksheets).

If you are serious about saving your marriage, you can't get it all on this forum. You've got to listen to the Marriage Builders Radio show, every day. Install the app!
