You know, friendly to each other if you happen to run into each other, but no active calling. It is all so sad, but a big fact of love life. Things change, people change and you just move on. For the most part, I've told my readers that friends are a very good source for love relationships. However, you do have to consider the possibility of lost friendship.
Love is a very important thing but so is friendship.
Love is always worth working for. Life is a risk and so is love. Here is someone you already like for various reasons. Hopefully through your friendship you have cultivated good communication skills, and this should greatly improve your chances at a good love relationship. Of course, this does not guarantee, that should your love relationship fail, that your friendship won't be ruined.
