These are all the ways I could interpret your question - some of the more commonplace ways people get themselves in trouble in the "too outgoing" department. Do you know when you're being "too outgoing" but can't seem to stop anyway?
This could be behavior you learned from a parent you've identified with, who acted this way; or it could be a kind of social naivete, from not having quite learned the rules (teenagers deal with this a lot but often outgrow it); or it could be the result of anxiety that you don't know how to contain but rather externalize and impulsively act out socially (This is the most common cause for someone in their forties.)
Either way, you can unlearn this and get better control over it by, first and foremost, listening to people. You want to be more subtle? Listen. Set your intention to find the other person interesting, engage in comprehending them, give them room to talk and then ask clarifying questions about what they’re talking about, and, short of doing this like a bulldozer, your responses will automatically become more subtle.
The other thing is becoming aware of when you have an impulse to be "too outgoing" and instead turning inward and handling yourself and your own impulses, rather than making it an interactive behavior.
Becoming adept at mindfulness meditation would probably be just the ticket. It's a practice of constantly turning your attention inward, back to your insides, rather than keeping it on social externals at the boundaries of your "self". This would train you to stop putting your jumpy insides on the outside, where other people have to pick up the tab for them. Of course, this would run counter to your whole way of being with people, so you probably would find it uncomfortable at first. But that doesn't make it a bad idea. It's a great idea if you have the motivation and discipline for it. So that would be my first choice for you.
If mindfulness is too quiet for you, too demanding, too lonely, then some simple relaxation would be a help. You could practice relaxing to our Relaxation & Wellness imagery or General Wellness and then put that relaxation to work in social situations. But you'd still have to become aware of what's going inside of you so you can interrupt the self-defeating social behavior before it gets expressed externally. So awareness is going to be a key component, no matter what. And that's a hard thing for somebody whose defense is to automatically and instantly translate their anxiety or discomfort into something interactive, before they even get to feel what they're feeling and identify what the heck it is. That's why mindfulness is my preferred method for you.
Of course you could also appoint friends or a spouse (if they're not too critical) to act as your social feedback coach, letting you know when and where you blew it and what you might have done instead. Some therapy and life coaching groups with a strong group process component can also teach you new behavior. But since it's going to come down to self-awareness, I would encourage you to do the mindfulness work.
You could join a mindfulness or vipassana meditation group; or we have some wonderful resources to help you at home. Jon Kabat-Zinn offers great instruction, as does Bodhipaksa in his excellent guided meditations. Give one of these a try and let me know how it goes.
All best wishes,
