The dating game involves a lot of hustle, and it is time-consuming and requires effort. Girls are very subtle when it comes to dropping hints, and it could get cumbersome as you could keep guessing for a long time.
The best advice for guys would be only to try if even she is also showing romantic interests and lest it is the call for you to move on. You need to watch out for these signs and save yourself from the injury of a broken heart. It does not mean you're bound to rot alone but you might wanna take care and watch your steps. So read on and take a minute to introspect afterwards...
That's the time to realise "quand toi et moi on fait boum,boum,boum" ain't gonna happen.
Let it be, dude. She's is definitely not the one. It's better to be single than to be with the wrong person.
