A good way to be more expressive with your girlfriend is to learn to start trusting her and believing in yourself.
The reason why you may not be expressive could be because you are uncomfortable about something. You may think that if you tried to be more expressive in some particular way, she would not approve.
That may worry you. You may also think that you simply don’t know how to do it because you have never been expressive in the past.
If your ex girlfriend told you that she would not meet up with you so as not to open up old wounds, there is a very good chance that she has moved on mentally from the relationship and doesn’t want to put herself in a difficult position.
She just doesn’t want to put out any more effort.
Meeting up with you may simply not be worth it to her.
People in your generation, the under 25’s, end relationships so quickly because for one thing, they have a lot more dating options today than their parents had.
With all of the social apps and social media sites a la Facebook, they have a wide variety of options in terms of meeting potential partners that many previous generations didn’t.
People in your generation are also in the age of instant gratification.
