If by stop trying, you mean stop pressuring her, then you are on the right track.
"Trying" is the last thing you need to do. Becoming a better version of you, stronger, more attractive, more self assured, a better all around person is a very good idea.
If stopping trying means moping, drooping, going poor me, then it's a really bad plan.
And your course of action for the near future should not depend at all on whether she sends "signals" or not. You are not doing it for her.
