It's important to know who you are, what you want, and things you are looking for before going into any type of committed relationship: The best way to do that is to date yourself! Every week, or when you want, take time for yourself. It sounds silly at first, but the only person who should know you better than anyone else is yourself!
Clear out an entire day/evening for you.
Make sure not to have any chores or errands or any extra work you have to do. The day/evening should not be filled with stress or constant reminders in the back of your head of something else you should be doing. Relax.
Dress up (if it's something you like!)
Personally, nothing feels better than when I put on my favorite outfit, do my makeup and hair, and feel like I'm the prettiest person in the world! Normally one would get ready to see someone else for a date or go to a party, but dress up for you! Dress up for your date with yourself :)
Get your favorite food!
Enjoy being with you and give yourself your favorite meal! Make yourself happy by driving to your favorite restaurant and getting your favorite thing on the menu.
Buy yourself something
If you have a little extra cash you're willing to spend, buy yourself something nice! Something small! Anything! Just as getting gifts from friends, family, and an S.O. can make you happy, buying gifts for yourself can make you happy too.
Pamper yourself at the end of the night
Take a nice bath or a shower, paint your nails, do a hair/face mask, read a book, watch some Netflix, paint, journal about your experience, meditate and do whatever makes you happy. Spending time with yourself is a great way to feel comfortable and confident on your own.
Now, go take yourself on a fantastic date!
