I guess it really depends who you are, you have to make the choice yourself. Tbh you can be a very happy single, if you have good friends and all that. It's not a taboo anymore to be single and be proud of it. Relationships can be good for something, but eventually they won't last for ever. Thats the part of it. Remember that anything that makes you extremely happy will eventually make you just as upset again, that the circle of life.
