Starting a new blog with a nagative coment is probably in bad form but I just have to say it; we all have a past both good & bad but if the first thing after hello that you want too tell someone new is how bad your ex spouse treated you over a decade ago then you aren't ready for a new relationship, casual or otherwise.
please go get a copy of a book called "Love Busters" and read it!. Yes in the storys in the book you will find your ex. the whole point is to find you, because then you can begin to heal and know that it's not going to happen again in your next relationship.
