Sometimes people (many people) are rude. They don't show up when they say they will, they say one thing and do another, they don't communicate. Frustrating to deal with.

Fortunately some of us work on communicating, we try to be reliable, we are kind and good. You'll come across this eventually. I guess the answer is to continue to be kind and good yourself. Eventually you will meet new people.

You want more contact and communication with your girlfriend. How does she respond when you just tell her this? No need to confront her or present your wishes emotionally, just ask, tell her this contact is important to you.

When it comes to trust, I think people need to earn our trust. There are people out there who are worthy of trust.
