<human>: My ex and I broke up back in the beginning of October, but then had an off and on thing for a bit until around the beginning of November when we went NC for about 2 weeks. When we talked again we agreed to stay friends for a couple more weeks until she told me she didn't want to be friends with me and she wanted to get over me. We then went NC for about 2 more weeks until mid December when she contacted me again and we had a long talk about our relationship and left on decent terms.  

Ever since then I've been distracting myself to deal with the pain and even when I look back on the relationship I realize so many red flags and how much I overlooked because she made me feel happy. I've started to almost loathe her in a way, but even though it's been about 3 months I still get anxious and my heart feels weird whenever I see her picture or someone mentions her. How do I get past this? I don't want to feel like this anymore. I've blocked her on everything and I haven't spoken to her since mid-December but every once and a while a friend might mention her or since we share mutual friends she might pop up under a "such and such has liked this". It just makes my heart jump for a second and I think about her, but then I get angry at her as well. How do I control this and stop this? It's annoying and I hate it.

Can you condense the text into three sentences or less?
<bot>: Ex-girlfriend and I broke up a long time ago, but I still feel anxious when she pops into my mind occasionally or I see a random update or someone mentions her.
