All you need to know.
There you go. There's no set way to 'be a boyfriend.' Do what feels right. If you still want ideas, however, some basics: be there for her, spend time with her, hold her hand, call her just to say hi. COMMUNICATION IS KEY! Biggest killer of relationships- assuming rather than talking. Even over the littlest of things. Don't take anything for granted. Ever. Other than that, things should just come naturally
