Perfect Madness!

....sometimes I feel that I do not really need a boyfriend. At least for now, as I am still young enough (EHM..) and just starting my career in a good company. There still lot of things that I want to achieve in my life, as an example, getting a better job than mine now (I do really like the people, but the culture really makes me stress), having wider network with more and more people from any background, having an opportunity to study abroad with scholarship, and may other valuable things that can't be mentioned one by one --> just an example about how greedy human is ~ XD

Maybe because of that, I feel a bit scared (or nervous) when a guy start to approach me. Well, I actually never met him. He knows my number from my lovely auntie at Surabaya (thank you, I guess? XP). He has called me once, and I think he's quite nice. But when he started to messaging me several days in a row and calling me almost every weekend, suddenly my will to know him further start to disappear.

Am I weird?
Is my excuse up there right? Or maybe all this feeling occur just because I have no experience with guys? --> somehow, I think this reason is better than the previous one :(

Any advice, anyone?
