On a whim tonight I looked at Andy's (ex-H) facebook tonight. Not sure if he's still here, but he's been in Minneapolis visiting his parents lately. They live about 15 minutes from where I work, and I have a huge fear of running into them. I'm going to be all panicky now until I know he's gone back to Florida.
I don't know why it worries me so much. The only time I saw him in Florida we walked right passed each other. I'm just afraid the next time won't be so uneventful.
Apparently his sister got married recently too. I know people's lives move on but for me his family's timeline stopped when we did. I wish I could congratulate her, she was really nice to me.

Re: panic attacking
I agree. I would have been in shock and scared to run into ex's in the past, but if I saw any of them now I don't think I'd really care. I think you're going to have to just wait this one out.
...and get off his Facebook! Every time you check his page you are dragging yourself back in. You aren't going to be able to fully get over all the stress and things until you completely cut ties - including checking his Facebook.
Agreed. Especially with the bolded part.
I prefer reserving the phrase panic attack for actual medical panic attacks.
As far as A is concerned, F him. Ignore him if you see him. Don't worry about him. He doesn't matter at all.
