I read somewhere that someone has trust issues in a relationship, I may not understand what has happened that the person develop trust issues

But what happened must have been painful enough to close oneself up, and not be able to trust the next one that comes along

it will definitely take some time to open oneself up again be it to trust, love or care for the next person

of course, opening up yourself comes with the need for you to open up your heart again

And that can be scary, because it leaves you vulnerable ... again

Vulnerable to being hurt, to be disappointed, to go through pain again

This is why the strongest are the ones who are willing to show their vulnerability, where others can attack or hurt them, or even to be shamed

So to sum it up, if there is something you want or be committed to get - in this thread, about relationships - what are some things that you are willing to risk?
- be hurt
- be shamed
- be ignored
- be disappointed
- or become an enemy

What you are willing to risk are the things outside your comfort zone

To have that growth or expansion of your comfort zone, one will need to be willing to take the risks, and then learn and that is how you expand your comfort zone

Then again, if something happens such as one of the risks, it is very easy to retreat back to your comfort zone because it is comforting - your safe space

That is not growing your comfort zone

This takes practice, and doesn't mean you do alone, you can ask for help =)
