<human>: I (23F) am having some issues that I can't get past in my relationship with my SO (25M). We met in college and dated for over 2 years, but once I graduated and moved for my job, things really fell apart. So we broke up. After 6 months, he contacted me saying he wanted to try again. I was hesitant because I wasn't sure what had happened while we weren't together and if the distance broke us up the first time, why wouldn't it the second time? Anyway, I decided to try again with him since I still loved him.

Now we have been back together for about a year and I just recently moved in with him since he graduated and got a job. Things were fine and dandy. I finally felt like our relationship was back on track. However, some past insecurities have slowly been resurfacing in me since moving in with my SO. While we were broken up, my SO had hooked up with a number of other girls and had a FWB relationship. I'm not saying I was an angel while single, but I did not go out on a quest to meet others like it almost seemed like he did. Anyway, my insecurities solely stem from this. I feel almost pathetic that things have gone so smoothly right after getting back with him. It's as if he first thought long distance wasn't worth it with me, so we broke up. Then he went out and saw what was actually out there. He didn't like it,  so then decided I was worth getting through long distance with. On top of that, I now feel self conscious in bed with him due to his number of sexual partners increasing dramatically (it tripled in 6 months...). We have spoken about these insecurities of mine before, but now I feel awful about them since I should have gotten over them a long time ago (and I thought I had). 

So my question is,  is there a way for me to really move past this? If so, how?

Can you give me a shortened version of the text?
<bot>: SO and I broke up after 2 years of dating, but after 6 months got back together. One year later and I'm still having insecurity issues based on the girls he hooked up with while single. How can I get over it?
