I'm 16 years old and I've been dating my 18 year old boyfriend for a year and a half and I can't seem to trust him. He's a really great guy and has never done anything to make me not trust him. But he went off to university this year and we've been continuing a long distance relationship. Its hard sometimes but we see each other on average once a month. I've recently started not trusting him because he's been messaging other girls, nothing sexual just normal conversation. This has been bugging be a lot because I don't understand why he has to talk to other girls, makes me feel insecure about myself and our relationship. I also feel like we have a double standard, I never talk to other guys and if I do he gets upset. So I don't understand why its okay that he does it. Why can't I trust my boyfriend, and how can I learn to?
