If some one goes to your profile and click on "Love" icon, you will get notification -> you can then go to that user's profile to click "Love" also if you want to do further iteration with him/her.

We will add a new feature at next version, when A loved B and B also loved A back -> system will send a notification like "You have a match" to both users then auto create a new message for them to start chatting.

ok sounds good if I can suggest putting a button in this view here people will not know to go to the profile and click hearts to fish this process
