Ok so I really like this girl on I had cl with?

but we dont have the cl anymore and so I can only contact her through myspace....so ive messaged her through there...and she answered me....and we exchanged like 4-5 messages...and then she didnt answer my last message to her. so like a month later i messaged back and said "hey u neva answered me bacc" and she was like "oh sorry" and so once again we exchanged like 4-5 messages and again she stopped by not replying my last message too her. now its been about 2 months since that...should I bother tryin again or should I just take the hint lol?
