Went through a devastating break-up last February. When we parted ways, she asked me if it was "OK" for her to call me. I said, "after you have put some thought into want you want, you can call me" I was grasping for anything at that moment. She replied, "No, she just wanted to do something as friends", I replied "I misunderstood your intentions, and that would happen again, so it would be best if we did not have any contact.

That was ten months ago, I have seen her around town, mostly when I'm out running, she will wave, and I wave back. Every time I waved back at her I regretted do it. Cooler weather is upon us and I joined a new gym 2 months ago. This gym has a pool and I decided to take adult swim lesson to improve my technique. Two weeks ago her and her new boyfriend are using the pool while I'm taking my lessons. I'm not giving her any attention when out of the corner of my eye I see her give a half hearted wave. I ignore it. She shouts my name and says "Hi". I look at her and said "hi". This really bothered me, I told her and I thought we had agreed I did not want any contact with her. I have put a lot of thought into what had happened, I'm disgusted with myself for being so naive, it is easier to see things when you are looking back on what had happened from a detached viewpoint.

I'm also still mad at her and the way she treated me. So I still do not want any contact with her, I don't even want to have a passing conversation about the weather. Her behavior really bothered me. Some friends said I should quit the gym, I considered it. But, why should let her control my life still. I had been considering taking a spin class, I have never taken one, so I was advised to show up 20- 30 minutes early. I had to stay late for work so I only showed up 15 minutes early, but the ex and ex's new boyfriend are already set up for the class. I ran on the tread mill instead. I finish my work out and leave, and realized I had left my water bottle back at gym. I return to get it, the spinning class has gotten out and when I walk in the ex is in the lobby, and she says, "hi" again. I really don't want to change gyms, this one is nice and it is the closest to me with a pool.

Should I just tell her I want nothing to do with you and quit saying "hi", treat me as if we don't know each other. There has been 10 months of no contact, I have not made any attempt to contact you, can't you see I still don't want any contact with you.

I would ignore her;if she says ''hi'' again nod politely and walk away.

No reason for you to change gyms,you should't have to adjust your life around hers.

Say hi, and keep going. Why make this into a great big drama? Don't torture yourself, just because you are mad. So what? Never act out of anger and frustration.

I'd say hi and keep going, but if it bothers you that much, tell her to please just leave you alone. She will then fully understand that she needs to leave you alone.
You don't have to make a scene, just tell her to leave you alone,
