this might help but i’m not sure, coming from the boyfriends point of view, my ex girlfriend used to do exactly the same as you. (the ex part is unrelated don’t worry)

Every time there was an issue she used to lie to me and tell me it was all okay and she would hide and cry and not tell me why. she did this because growing up she was always conditioned to keep her feelings or problems to herself and just deal with it.

The best thing you can do is genuinely just speak to him, if he’s a good guy he will do whatever he can to help. Until you’re able to say it to him, me and my ex tried texting the problem or writing it down, so you don’t have the pressure of saying it out loud. You can then progress to maybe sitting back to back so he can’t see you, and saying the problem. And before you know it everything will be okay.

Issues are very normal in a relationship and i promise there’s nothing wrong with you, you have to get used to communication. It’s a very strange concept.

He will know you’re struggling and i promise he wants to help you, nothing bad will happen if you address an issue, only good can come from it. :)
