If you want a girlfriend, youll be more selective; if you need a girlfriend, anyone will do.
I's like needing and wanting anything else. For instance, Du you want a bandage to cover a scratch, or need a bandage to protect an open wound. The covering of the scratch is nice to do, but isn't a need. You need to eat, you want tasty food. You want a girlfriend, and that is nice. If you need a girlfriend, then that means you aren't comfortable with yourself and maybe you should work on that first.
Be logical about it - what's the difference between need and want (forget the girlfriend part)?
Needing a girlfriend sounds desperate and you are likely to settle for someone just because they are available. Wanting is not desperate, just says you are ready and looking.
needing is desperate, wanting is losing hope
Need and want...lol
