I've never been in a relationship before but would love to be in one. Every time I get asked out I say I'm not ready to be with someone.
Relationships can be intimidating. Why do you always turn down their invitations?
It's because I'm also very selective about who to date.
Being selective about how you want to date is perfectly fine. It's completely up to you to choose who you want to date or if you even want to date at all. You need to live your life in the way that makes you happy!
I have standards, in a way that I find other people to be lacking.
It's acceptable to have high standards when dating since it's your life and you should choose who you want to be spend time with. However, it's important not to look down on other people.
