4. She does not like boys’ nights out
Once you start dating someone, you must look up whether they make any objections on your night out matters or not. If she insists you on stop hanging out with your friends then you must not marry her! She might think that boys get in trouble together or she might not like your friends or any other possible reason associated to it. But that should work as a negative marking for her. Your girlfriend or future wife must not have the right to choose with whom you should hang out or be friend with.
