Believing new things

Please help me draft a new belief –
My current situation is that my husband and I are on verge of separating. We are always walking on eggshells and hardly spending time with each other. My hope is to reach a stage where I can be friends with him, be self confident and enjoy our relationship together.
The thought I want to believe is – I am in a happy and healthy relationship.
Current feeling and thought on this – disbelief, we don’t even spend time with each other. He has ruined my career and spoilt relationship with my family.
Counter thoughts – we can decide to spend at least 15 minutes together at dinner time. He has helped me get awareness about my family so that I can make choices. He has been nudging me to get my self confidence in career.
Massive action – spend 15 minutes at dinner time discussing highlight from day.
