Most valuable in relationship is devotion for you. You are very [__ separator__] loyal to your companion and expect the same from your partner. If you suspect something bad even for a second, it's unlikely that you will continue to have this relationship since trust is paramount to you, and if it turns out to be undermined it's difficult to change anything. If your partner will be faithful to you, then you will do everything on your part for him to feel the happiest.
