Communicate, communicate, communicate and then communicate some more.

Regardless of the nature of the D/s relationship there is still a partnership and support structure that goes both ways Doms have it a bit easier being able to overtly demonstrate that.

You love this woman you have chosen to be your sub and who has consented to being yours. Then love her, support her and guide her. Just keep her past in mind as you take her into your joint future.

For communications, as an example, set aside a joint activity or just a hour or so a day where she is free to speak with out repercussions. Reinforce that while she is Yours she is still the woman who you fell in love with and want to guide and protect.

Submission does not mean that the sub has to stop being them self.
