<human>: Can you give me the gist of the text in a nutshell?

Does anyone have advice for really getting over an break up from a long time ago?

Background: In 2008, after my former fiancé called off our wedding (May 2008), I started dating new people around October.   I was with my ex-fiancé at the time for 8 years (since HS).  When I started dating people, I met someone who I REALLY enjoyed spending time with but wasn't ready to make a new commitment but "dated her for a few months (Lets call this person Jessica).  I stopped hanging out with Jessica after I met the next person who caught my interest (bad idea but felt right at the time since I wanted to see what was out there).  Fast forward and we used to keep in touch and hang out from time to time up until about 2 years ago.  Getting back together never worked because we were in relationships, one of us didn't want a relationship, etc ..basically the timing never worked.

A couple of years ago I met someone and now I am engaged and love her a lot. There's nothing I would do jeopardize my relationship now.  However, I do find myself checking out Jessica's Instagram.  We had a lot of things in common (got along really well, outdoorsy activities like hiking or skiing, watching certain sports teams, similar values) and any time I see a related post I cringe a little.  That feeling lingers in me feeling a bit down.

I know the next question will be what about the person I am with now.  I love her and we really get along.  I guess the thing that's different (not bad, just different) is that we don't share all of the same interest like I did with Jessica.  We share enough and do things together but aren't into exactly the same stuff.
<bot>: Met a girl after long term relationship. Wasn't ready at the time. Fast forward 8 years, still check out her IG from time to time. Am now engaged and still regret the breakup a bit.
