When you find somebody you really care about you want to experience life with them, and grow with them. I'm in my relationship because I love him and everything about him, and I get to build my life with the man I'm in love with
But I thought you said you need to be married to have sex?
You shouldn't have sex until you are married. However you don't have to be married to have sex. Like I could just go for a drive, pick a girl up and rape her to have sex. Or just call a whore. So you really don't need a relationship to have sex either.
You get to find someone who finally understands you and accepts you for who you are and all your qualities
You look forward to something in life/have motivation to wake up
You have someone to talk to about your interests and whenever you or they feel lonely
You have someone to admire, your better half allows you to think in new ways and see in new light
They make you a better person
You can look into their eyes deeply and say "I love you" and (hopefully) hear it back
You can hold hands on walks and just admire their little quirks and qualities
You can share good and bad times with them
You can celebrate valentines day and Id give them flowers and chocolates
Thats more than enough for me
See I used to think that way and then I met @RoshniXRoss and the c*unt before him, there's no point to relationships OP unless you like making your life living hell.
