I kind of find it ironic my single friends long to be married and alot of my married friends look at the single ones with envy.
Try to enjoy where you are at now. If you're single it means you can make decisions without consulting with anyone. You can do exactly what you'd like to do. You can have a wide variety of friends and always be open to meeting someone new.
Being in a relationship is great too - don't get me wrong. But there are pros and cons to each one.
I had a single friend who had been waiting to buy a house until she had found a partner. Well, after a while she decided to just buy the house by herself and stop waiting around for a "man" to start living her life. She actually is dating her swing dance teacher now.
Go out and enjoy life (wherever you're at in the relationship category). A partner will just compliment a happy life.
