What steps can a 29-year-old man and a 27-year-old woman take to rekindle their love and find happiness together?

My boyfriend and I have been through a lot together over the past three years. Our journey hasn’t always been easy, but facing challenges as a team has made us stronger and deepened our desire to be together. We share our home with four beloved pets, creating a space we enjoy, but we've also encountered difficulties. His avoidant attachment style has sometimes undermined the trust and security I seek, especially as someone with an anxious attachment style. We're both committed to rebuilding that trust. However, I’ve sensed that the spark in our relationship has dimmed, and I desperately want to reignite it. We're working hard on our relationship, and perhaps it just requires patience. I would welcome any suggestions to help restore that feeling of love and excitement. I’m not looking for a new honeymoon phase with someone else; I want to rediscover that sense of love and wholeness with my partner.
