The answer is both, yes and no. If you like it so much, yes, why not, go ahead and try again. But no, don’t do it like you did last time. Find another approach, learn from your previous experience. If you haven’t, why not try the following?

Control yourself if you want to have another chance with him.
First of all, you need to make sure that you straighten up and not sulk over the previous rejection. You shouldn’t let him see that your spirits have dropped or you’re so desperate that you go into fits of emotional outbursts or periods of depression.

Give yourself some well-deserved pampering.
Going to the spa and/or salon will help you get a fresh start. You will need to arm yourself with a self-confident disposition. Men like beautiful and confident women, so go for it. Regular exercise like going to the gym or other physical activities like swimming, badminton, cycling, etc. it will help a lot

Open up your social life.
Just because you’re looking at a guy doesn’t mean you’ll limit your social life to him. Let other people into your life, make friends, let other men appreciate you. Sometimes all it takes is another guy to notice you for him to realize you’re worth chasing.

do not take revenge
Don’t date other men for the purpose of making your target guy jealous. Do not take anything against him if you intend to win his heart.

Live a great and productive life.
You should not let your life deteriorate just because of a previous rejection. What you need to do is keep yourself busy: go into a small business, volunteer at an orphanage, etc. This would heighten your sense of self, which, in turn, will increase your feeling of self worth.

Make him realize that you are a girl worth conquering.
You are beautiful, confident, productive, helpful, independent, and interesting. There is absolutely no reason why you can’t attract men, and this could very well include your target guy. And there’s no reason why he shouldn’t think he’s missed out on a winner.

Don’t chase or be too anxious.
Although your strategy this time doesn’t include actively trying to catch it, you shouldn’t ignore it either. Let him feel that you still like him. However, you should not be too anxious. Let him work to earn you for himself.
