he said i got too attached (aqua male/leo female)

I've been kind of hanging out with my ex-aqua for a couple months. We broke up 4 months ago.
Every time I bring "us" up, he shuts down but last week he told me I had gotten "too attached" and that's why he split.
The thing is that now he is behaving the way he did when we first got together. But says he's going to be alone for a long time.
I don't get it. And he was visibly upset when my response to him saying that was that I wasn't.
could anyone tell me wtf hes doing or thinking better yet!

What he is saying is that he does not want a committed relationship but will have fun with you as long as you accept this boundary. He was clear with you and that is honorable, now all you need to do is accept what he said at face value and not measure his words/actions using your ruler.
Aqua Men do have a tendency to go through a good portion of their lives 'unattached'.

@fixedwater, I apologize for the delay in replying but thank you for clarifying. I tend to try and read a person's body language to see if they're being honest.

That's obviously an issue I need to deal with.

Thank you though. I am so grateful to have found this forum. Each time I come on I learn something.
