Liking someone is more like enjoyment to make yourself happy. Loving someone is more like a responsibility to make the person you love happy.
Liking someone is when the relationship is getting hard you may give up and go find a new one. Loving someone is even when you know this relationship is going to be hard, you still try your best to fix it, for keeping them to stay with you.
Liking someone is conditional, if you can’t get anything in return you may give up. but loving someone is unconditional, you want to give your best or anything they love to them, even you know there is nothing that will be returned.
Liking someone is you enjoy the present with them. Loving someone is you enjoy the present and also plan the future with them.
You can like a few people at the same time, but you only love one at a time.
