Seeking help together
Sometimes, problems exceed what you can manage alone, for example in the case of infidelity that you would like to overcome. It's OK to seek external support, whether from a trusted person or a professional. "I think we could talk about it to someone together, what do you think?" is a way to show that you are committed to your common well-being.
Situation of mourning
Faced with a loss in the family, instead of feeling helpless, take the initiative to gather support from your friends and family. Organizing a vigil where everyone can share their positive memories can be a way to support your partner, but also his close entourage.
Supporting your partner and preserving yourself is finding this delicate balance where everyone can feel supported, understood and valued. It is this dance between giving and receiving, being there for the other while taking care of oneself, that creates a deep and mature relationship.
