It’s easy to tell when you’ve stopped loving someone by looking for these signs:
1.) You no longer want to do things together. i.e. being around your partner.
2.) You no longer enjoy any affection and pull away from your partner.
3.) You find yourself thinking of future plans and don’t think of your partner in them.
4.) You find yourself spending more time at work or with friends.
5.) You start to pick petty arguments with your partner over nothing.
6.) Communication breaks down.
These are just a few, but, are big indicators of when the love stops or that something significant is going on.
