Hi, littleblondie! I'd like to join formflier in saying welcome to the family!
I'm so sorry you're going through all of this.
When he isn’t like this he is lovely! Caring, kind, tells me he loves me, tickles me to make me laugh, breakfast in bed. I am beginning to realise tho that I’m being emotionally abused. I don’t think it’s intentional I just think he is genuinely in severe psychological pain.
This, in particular, stood out to me in your post. My H is similar. When he's on stable ground, he's considerate, affectionate, loving. When he's dysregulating, though, he's emotionally and verbally abusive. I, too, don't believe those times are intentional. It seems to be pain and poor coping mechanisms.
I do hope you're able to find ways to care for yourself so that you can "replenish."
I'm not familiar with healthcare in the UK so I can't help there, but is there a particular area of your relationship that seems to cause the most trouble right now? Something that tends to really set him off? Sometimes zeroing in on one subject can make an overwhelming situation a little more manageable and we might be able to help!
