Oh, i see... I thought as it was a singles forum so that was clear what kind of trust I was talking about (please forgive my english).
It is, but there are a lot of topics discussed, and not all are related to being single.
As far as trusting in relationships, well, relationships are a risk, period. You have to be aware getting hurt is a possibility no matter who the person is. Even if the person never does anything wrong you just may not be compatible and things not work out.
I have been devastated many times romantically, yet I'm in a relationship now. It took some time for me to trust them, it didn't happen right away. But they earned my trust over time.
But I've been in that place of fear and heartbreak and not wanting to trust again. It's lonely. Not because you don't have anyone, but because you've made yourself lonely through isolation.
My advice, take some time away from the idea of romance. Not out of fear or hurt, but to heal. Don't make any decisions about your attitude about romance right now.
Choosing to not date is not a bad thing, but your motives can turn it into something bad.
And rememeber finding someone is not the most important thing in life. What you do with your life, whether solo or with someone else, is what matters.
