I don't see his behaviour as abusive, but that's just me. I see it as needy. For me, abuse is when you feel legitimately scared of a person / fear for your safety - physically, emotionally, verbally, financially or psychologically.
Regardless, it's at the very least about compatibility.
The hugging in Aldi thing, neediness, babyish voice, keeping notes, eagerness, etc. I'm female, but I date women, not men; and loads of women I've had relationships with have done these kinds of things. If I wasn't into them, I'd feel suffocated. If I was into them, I'd largely probably find it sweet.
I don't really like the idea of telling someone they are needy/clingy/whatever though. It bothers me. I feel like in relationships, it's about telling the other person how you are feeling, rather than putting them down? Like "I feel suffocated / I don't like baby talk / I'm not sure we're on the same page / I'm not into PDA / I don't want this much physical affection".
I don't know. That's just my take on it. Sounds like you have the ick. Nothing wrong with that.
