Confession

I have a weird attraction to an ex even though I've moved on and wouldn't get back with him. I'm pretty sure I love my new boyfriend, but I think of my ex sometimes and miss certain things we did together and how comfortable we were with each other. We have a lot of inside jokes and personal stories that I always wish I could share with him again but I can't. Any thoughts on how to only focus on my current bf? Also please feel free to comment your own confession; no judgment zone.
