>I decide to change my name into my real name, Mark.

Nice to meet you Mark. I'm Anonymous.

>I won't be looking hard for the one special girl. Should I?

No. You should start by posting this in /love/, that's where itbelongs. Second, you don't even have a clue what kind of person suits you, don't waste time agonizing over it. But really, if you are that eager to start a relationship, why don't you use a dedicated website, that's what they are for, and they work well, if you take the time to understand how.
