When you really love someone, it is hard to keep your jealousy under control. You do not want them to leave you or figure out that they`re happier with someone else, so whenever he talks to another girl, you freak out.
Checking his phone
It`s normal to ask him who he`s texting when he`s sitting next to you and even to try to take a peek at the screen, but you shouldn`t feel the need to read through all of his texts and emails when he`s not around.
Multiple Calls
It`s nice to call up your boyfriend once or twice a day to chat. However, if you`re calling him every hour in order to eavesdrop on the background noise, your relationship is in jeopardy. If you don`t trust him to tell you where he is, you two aren`t going to last.
Quizzing him
When he comes home from his friend`s house, do you quiz him about what they did, because you don`t believe they were actually together? It`s fine to ask him questions out of curiosity, but you don`t want to ask and ask until you find something you can yell at him for.
Insecurity
Whenever he looks at another girl, do you end up crying? It`s normal for humans to look at other humans, even if they`re in a relationship. Obviously, if he`s doing something inappropriate, you have a right to speak up. But if he`s just smiling at your waitress to be polite, don`t ask him if he finds her prettier than you.
