Start a paid feature apart from xtra and unlimited which is relationship focussed . Currently your relationship filter does not work because guys select multiple option so there is no way to find exclusive relationship focussed people

Here what you should do

1. A paid relationship focussed feature something like Grindr relationship
2. Make face verification and government ID mandatory
3. Make it paid to filter unwanted people

There are many aaps trying to create seperate aaps but if Grindr already has user base why not try this . You can experiment it to launch in india for start
