It is a normal reaction SpecialK. I did it and still occasionally do it. Don't let that person (who by the way was using your H and being used by your H) take up precious space in your brain. They are nobody and frankly are just as lost as the MLC'er. It is not a relationship and it is not fun and games. There is a lot of turmoil in those unions, how could there not be.
Here are a few things that worked for me to STOP thinking about her and my H. A rubberband on my wrist. I snapped it hard everytime I would wander down that path. Visualizing a stop sign. Frankly shaking my head in disgust and shaking the thought out of my head. I found the more I talked about it to other people LBS'ers, counselors the more I focused on it.
She is nothing but a symptom. A symptom of a disease, cold, however you want to look at it. Here imagine her as mucous. Eww that's a nice visual.
We have all compared ourselves to the OW. Their union has nothing to do with beauty, sex, and only has to do with attention and the chemical rush that they get. Frankly most of them are affair downs. My H has told me since OW is out of the picture that he, at that time, didn't care who paid attention to him. It could have been anyone, he didn't care.
I know you have probably heard this before, but it is something that took a while for me to really process. Your H is the exact opposite of what you knew. Thus, he attracts the exact opposite. Think about it, they are two needy, lost, pathetic, lonely, depressed, addicted (I could go on) people enjoying each other! I think NOT! Maybe the first few weeks/months but it goes down hill quickly. Think high school relationship gone bad (the thought of being in one of those again sends shivers down my spine!)
Focus on yourself. Find what you love about you. If you don't know, figure it out. Make time for yourself. For example, I had and still do have a low self-esteem and social anxiety disorder. I was extremely codependent on H. I forced myself out of my comfort zone. I go to the gym alone, run alone, hike alone (oh, OK, I do take my horse/dog with me sometimes
I have made friends without my H, gone out to dinner, drinks, socialized without my H. I applied for jobs and got jobs that I didn't think I would be qualified for. I took risks and wasn't the shy, I will take the safe path girl. I did a 180 on the things that I always wanted to improve about myself. As I get stronger, I focus less and less on OW.
Your sitch is obviously not the same, but I give you these examples, because the pain of obsessing about this vile, lost, person is not fun and only you can control you and your thoughts (another hard lesson to learn).
I guess what I am trying to say and what took me a long time to learn was focus less on OW and MLC'er and more on you. A strong you gets to drive and gets to make choices. Use this time to build up you.
Hugs,
Sassy
