It may be that it is just his nature not to trust people he hasn't known very long, but it is very likely that he had a bad experience with a woman who betrayed his trust and he doesn't want to be burned again.
It means that he thinks you could lie to him and/or betray him.
Answer
If you have given him a reason to not trust you, that could be why he says that. In that situation, it will take time for him to see that he trust you again. If you haven't done anything that would make him think he cannot trust you just reassure him that he CAN trust you, then prove it. There are many different reasons why people find it difficult to trust these days. The only thing that I know of to do is to prove, over time, that you are trustworthy. If you have not given him any reason not to trust you, it could be from other things in his life that he has experienced such as others betraying him. If that is the case, just be patient, let him know that you would never do anything to hurt him, and let time pass so he can see for himself that you are trustworthy.
Trust issues.
I would ask him what he means by that.
He says on Instagram that he has a boyfriend, but doesnt say who.
it means he useing u kind of srry to hear that
He thinks your the right one but he doesnt actually know.
Basically you need to get over it and make him jealous by getting yourself another boyfriend, who is more reliable and who you can trust.
One of two things: 1. Exactly what it says she doesnt want a bf. or 2. She doesnt like you and is interested in someone else.
your boyfriend wants to know he can trust you ex: you got me if i fall
love doesnt allow him to get away from you
if she says that to you, she obviously doesnt like you
Justin Bieber says hi.
you should tell her if she doesnt care whats the pont trust me I'm a girl
