How do I tell my boyfriend I'm not happy?

Take your time to think over how and when you can tell him that. Before doing it, make a list of which things are making you unhappy, since probably he will be looking forward to know how he can change that. If you don’t love him anymore, then it’s a bit harder for him because there is not always something to can change to make the situation better. Anyway, I think it is important to have a clear and schematic list of what’s wrong in your head because telling him, it will help clarifying.

In a real heart to heart conversation where the point needs to be brought across clearly but respectfully. Your happiness as well as your boyfriend's is very important~

Calmly sit with said bf and state that you are not feeling happy, recognising that they are your personal feelings.

Talk to him about how you're feeling. Make him understand that you are unhappy, and he will support you and try his best to make you feel happy again.

Maybe you could sit down with him and explain your reasons for not feeling happy anymore. Discuss it and try and make him understand

Just be as honest as possible. It is difficult, but remember that if you're not happy, he won't receive the best from you. And that is not your fault! I went through this a while ago, and although it was hard, it was better for us to part.

The key to any relationship is communication. It’s best to just sit him down and talk frankly about the issues. If you worry you’ll get off track and emotional, maybe write down in bullet points what you want to say and refer back to it.

For me honesty is key to everything, relax and take your time to talk to him tell hik what went wrong and try to work it out

First, make sure you understand why you're not happy, so you can convey it well to your BF. You might want to take some time and write about your feelings in a journal - it may help you to clarify exactly where the unhappiness lies.

Just try and be completely honest about what's going on in your head, he can't help if he doesn't know and keeping it to yourself will make you even unhappier
