Do you want to describe some of these advantages?
1. Companionship
2. Tired of looking for “LOVE”
3. Don’t believe in or want LOVE anymore
4. Financial reasons
5. Caring for someone enough, even though love isn’t there
6. common goals
Most of these could come under the umbrella of “marriage of convenience”, an old-fashioned term. Love is not necessary for a successful marriage. Also, love can develop from a caring relationship.
