Train to live in a family.
Distinguish between preparing for a family and building a family. The decision to build a family — we live with one person. We train — it’s normal if you meet with several and learn confidence, care, attentiveness, learn to be interesting.
Should this be a secret? Not everyone understands this, but you can share with some, they will still tell you how best to behave.
When you decide to close the training, you just come with eyes stunned with happiness and a huge bouquet of flowers and tell that you have found your love and happiness. Nobody will object to this.
