Renee, You are obsessed by what they both are doing. His so called friends/co-workers have talked to you and you may or may not have responded to their comments about your xh. You've been to his home, you are looking at the my space page and reacting in a very upset manner (for which I can understand). However, if you read up on stalking, you will find that you've been doing some of the things that stalkers do....I'm not saying you are doing it intentionally, but it goes w/o saying, you are still very obsessed by what they are doing and reacting to their behavior and comments. Stalkers follow their prey, they want to know what they are doing and with whom all of the time. Stalking isn't always about being up in someone's face it can be done via the internet, telephone, letters, gifts, drive bys, peeking in windows, having conversations w/friends, and following their every move and being where they are. If you make your xh angry enough, he will slap you w/another restraining order and very well cite you as stalking.
Renee, you may find yourself in a situation, whereby you will be thinking about that ring and it will fester until your anger builds up and you very well may say something that you shouldn't. Your xh is laying low right now and for once in a long while, he's not threatening you w/another restraining order. Stay away from their my space pages. None of us want to see your anger build and then your emotions take over and you say or do something stupid. We've been down that road ourselves and learned that it's not worth the space in your head.
Listen to what the posters are telling you here. None of us want to see you dig your hole any deeper w/your xh. Leave them alone, forget about them for a while. Their my space pages are like an addiction for you. You are curious and yes, nosey....there's nothing at this time to be nosey about...he's not your h any longer and he will soon be her new husband and she his new wife. Some day, if the dust settles, you and your xh could be on a friendly basis in respect to the kids that you had together, but it's not going to happen any time soon.
Please, please let him go for a while. All you are doing is upsetting yourself and getting angry. Find something productive to keep your mind off of them.
I do hope that you will seriously listen to the advice the posters have been providing to you. You've been given excellent advice from some of the best people here. If you do nothing else, print off the advice you've been given and read it over and over again until it all sinks in.
