I'm a single girl and I have never been in a relationship, it sucks seeing couples holding hands and not having anyone to hold mine, It just sucks not having anyone in my life that loves me in that way.
Hey. Algs some people feel like that as well. Try to find someone that you'll love and he will love you back. It might end up well who knows. You don't always need a man in life. Don't feel pressured by it.
Love comes in the most unexpected places, while it's alright to actively look for a significant other, it's always best to work on yourself, to better yourself to be the best version of you. This is very important. Also I have to say that love comes in different forms, not just physically. Don't be jealous of them, there are many things you can be proud of, not just be in a relationship. You might not realize it but there are in fact many people who loves you.
