Hi msg.
You are right in that everyone has ups and downs. That is understood. But I dont think you should overly worry that someone will misunderstand something you may say and be scared away.
Remember, girls, for the most part, have a lot of brothers and they know in family life there are all kinds of ups and downs. They also learn that family loyalty remains through thick and thin.
You have no choice but to be real and honest. Dont think someone will be scared away. Being disonest and disingenuous are what will scare a girl away. They are smarter and more inuitive, and also have their ups and downs and may also worry if you may be scared away.
It will all work out.
Hatzlacha!
