One of the biggest things that hold someone back from expressing themselves and how they really feel is trust...it's not about touch but rather trust and believing in yourself. A huge reason why many people aren't expressive is because they are uncomfortable about something. Think back to the last person you started dating that you held back from...why was that?
So you've been seeing your partner for a while now and you've been missing them a lot lately...now you're wondering why you're missing him when a few hours pass by? Well the most likely answer is that you are becoming emotionally attached to them...your feelings do get stronger over time and this happens when you are especially close to each other and tend to share almost everything.
So you've been sitting around lately working out where your relationships went wrong and decided to pick up the phone and text or call your ex saying you wanted to catch up and find out where it all went wrong. Before you even know it, they've responded saying they don't want to meet up because they don't want to open up old wounds.
There have been many times I have sat either talking to friends or even a psychologist or two and they have told me that my attraction to an older man or dating older men has something to do with "Daddy Issues". Anyone who has been or is currently going through this would have heard this line before themselves. I can say in my experience, it's not true.
