I'm really glad the hugs made you feel better! That seems like a disturbing dream. In my experience, recurring dreams about one subject are a way for my subconscious mind to get my conscious mind involved, to get me to pay attention to my thoughts and feelings.
I wanted to quote some of your posts, so that you might be able to see what I am seeing. I have snipped the statements that stand out for me, and bolded the bits that seem most telling.
He has completely forgotten about it, I do not think he has ever followed it.
I know this partner has hurt me before through forgetting about other boundaries.
And it's not his fault, I am stupid and overreact about things- as for example this. I know it's not important. Yet I'm still starting a stupid thread about it anyway.
I did at that time. I said that I... was not comfortable texting other partners when with him and vice versa, that it seemed disrespectful and that I wanted to be present with the person I was with- and that I would prefer he stop sex to deal with whatever the important issue was, rather than texting during. He said that... it was completely okay... and the other rule had been stupid.
I hate that I have to jump up and down about boundaries for fear he will forget or ignore them or carve out exceptions, and that I can't trust that stuff he says is important is actually important.
And that I have to be the uptight boundary-setting one and he gets to be the free-and-easy happy-go-lucky chill one.
I am likely to be overly-strict...
...basically I'm just generally unreasonable.
I am oversensitive and he won't notice if something hurts me.
Probably he's right, probably his preferred rules are the right ones.
I could well just be overreacting to small things. He is a good person and is likely in the right. It maybe makes sense for him to make the rules...
unintentionally forgetting about me- I was a kind of prop... not noticing that I was doing so because his mind was elsewhere. It was ages ago and I should be over it...
In neither case was harm intended... he would not have done it if he had known it would hurt... he just didn't see it as a problem. He just thought the texting rule was obviously stupid and saw no reason to have it.
...if it turns out he needs it to be happy and comfortable around me, or if getting that means I would have to kick up enough of a fuss to hurt us, I do not want that.
He keeps agreements if he thinks they are important, to me or him.
I am not very attractive and this is understandable...
He will check it- and I often object and he will stop when I object...
I feel safe and like I can trust him- unless he forgets or doesn't notice when something is wrong.
He can be inconsiderate accidentally but reacts well when this is brought to his attention in a way that he understands how serious it is- I just wish... that it took less for him to notice something is wrong.
He says it is not because he was bored and not because I am unattractive but instead because he sometimes finds it hard to put life down, he thought it would be okay.
...I got unreasonably upset...
I am... a bit sensitive so it probably is all a bit overblown and dramatic-sounding etc.
I had been getting a bit over-upset.
...melodramatic... foolishly stressed by all of this.
Though you may not be aware of it, there is a clear pattern to your relationship, or at least to the way you describe your relationship. It seems that there is a power imbalance, in which the agreements the two of you make are not respected. It also seems as though you downplay the seriousness of this, painting yourself as unreasonable, over-emotional, melodramatic. You describe events that myself and other posters have strong HELL NO reactions to, but then backpedal to excuse your partner.
I commend you for seeking support and opinions here. This is an excellent community, with a wealth of varied life experience. Sometimes, we will ask for help or advice before we are ready to accept it, and it's okay to be wherever you are right now. I hear you saying that you are not ready to leave this partner, that you are happy, and that you feel respected. So I will just gently point out that it doesn't sound like a happy, healthy, respectful relationship.
It can be difficult to reconcile strong love and attachment with poor treatment, especially when coupled with self-esteem issues. Please remember that it's okay to disagree with your partner, to set boundaries for yourself, to expect that agreements will be honored. None of those things make you oversensitive, stupid, or melodramatic. What makes you feel as though his needs are more important than yours?
