My boyfriend is acting totally crazy? What can I do?

he's just really, really jealous and insecure. you should definitely sit down with him and talk to him and make him feel secure and loved and trust you that you hanging out with one of your best friends should not threaten him at all. and after that, he should warm up to the idea of being able to meet him himself to ease his insecurities about this "other guy" in your life. so yea, if you want him to not act so crazy over your friend, ease his mind. hope this helps.
