We fight every week

It looks like you have quite some problems. If you want this to change, I would definitely recommend relationship therapy, or if not, therapy for yourself.

When I read your story, the problem is not only on your side. Your boyfriend doesn't seem to have a healthy grown up response to certain situations.

Smash a plate to the kitchen wall out of anger? Seriously? That is not a healthy grown up response...

You could divide your situation in three parts.

1) How you feel and how you respond to him.

2) how he feels and how he responds to you.

3) How you relate yo each other in your relationship

When I read your story, professional support is needed. If you do not want that (yet), than start some self observation.

You could ask yourself the following questions:

1) How would I like to respond in certain situations?

2) Am I actually happy in my relationship? If not, what can I do to feel happy again?

3) How would I like my boyfriend to respond to me in certain situations?

And try to start a conversation with him on a relaxed moment, where you can speak to him from a grown up and autonomous space. Share with him how you feel and what you would like, without forcing him to do that.

And the other way around: ask your bodyfriend to share in a calm way how he feels and what he would like, without forcing you to do that.

I wish you good luck.

Thank you for your reply, I know that it is not just me. I just would like to learn to deal with our conflicts without getting completely stressed out all the time.

Point 1 I like... how would I like to respond in certain situations. I think there might be the solution to the problem.

I know that my emotional responses, my sensitivity is bringing it to a peak. That's also what he always says... when he reacts in a certain way I shouldn't take that personal. But that's what I find difficult... I cannot handle the screaming...
