MateMate - App idea for determining how happy one should be in a relationship

There's an idea I've been kicking around for a bit involving a dating app or social app that uses natural language processing. The idea is called MateMate, and it would essentially allow someone to enter a message exchange, or a journal entry for a relationship, and use the app's language recognition to compare the exchanges or logs to those of a similar person in a relationship to determine how happy someone should, or could be in their relationship, based on the language that their partner uses towards them in the relationship. <br><br>This app could be used to show users that they're in a relationship with someone that doesn't communicate with them as a partner should, to help them recognize verbal abuse by comparing the language their partner uses to them with the language a partner in a healthy relationship would use, to evaluate communication in a relationship, and to identify non-verbal or verbal communication that is potentially abusive. <br><br>The app could also potentially be used as a tool or companion app for a therapy program or counseling or therapy group for those who have been a victim of abuse before, to help them identify healthy communication in a relationship. <br><br>The app would need a way to collect logs or message exchanges from the user in a way that doesn't require a lot of work on their part, but makes it easy to collect a varied set of data, and would need to be able to analyze the language, tone, and intent in a way that helps to identify healthy or unhealthy communication patterns. <br><br>This app could be used to help a lot of people, and could be a very useful tool for identifying unhealthy communication in a relationship. <br><br>Any thoughts on this idea?
