Most are scared of getting close, especially if they have been hurt and betrayed before. My mother uses saying all the time and one being...
it's better to have loved and lost than not to have loved at all...
It's true, i except it and have only just gotten through heartbreak where I am not interested in the slightest of seeing this man again because of the pain I felt, however, I don't regret having that time with him. I learnt from this experience and it changed me in good ways too.
Am I too scared to go down this road again? Possible, I will be cautious with the next man I know but I will also try to not let the previous one effect the new relationship. It comes down to living and learning and growing with yourself.
There's never a guarantee that you won't get hurt or even hurt the other...
