First of all, stop reading his Facebook messages. If you can’t, since he gave you his password, I’m assuming with the understanding that you would use it, ask him to change it because you did use it, and it made you uncomfortable.
Second, pay attention to his behavior. Just because you’re in love with him, doesn’t mean he’s in love in the same way, at the same time, with you. It sounds like he still needs to test the waters with his female friends and this is upsetting you. It doesn’t sound, from what you wrote, like he’s cheating on you, but he’s not acting as committed as you had hoped he was, because you see him talking to his female friends.
One of the things I write about in Think & Date Like A Man, [url]https://www.askapril.com/relationship-dating-advice/think-and-date-like-a-man.html[/url], is that you can tell a man is serious about you when he starts acting like he’s part of a couple. That means hanging out with other couples instead of single friends — and definitely instead of single female friends! Your boyfriend probably enjoys dating you, but isn’t ready for the same commitment you are.
