You are 25 years old and every possible human interaction asks you the annoying question: When do you get married?
You do not want to compromise for anyone
If you can not tolerate a sink full of dishes and wonder how you would feel if you changed your vows with someone, then it is best not to do so. Believe me, you are not selfish at all. It is your life and you decide
Relationships are more of a problem for you
You have not met a person who “completes” you, and you love freedom.
You have big problems with the engagement
They are normal things to have. You can not imagine living a life with a person and are much more sensible than just getting involved.
