<human>: Can you provide a brief overview of the text?

I've been dating my boyfriend for 8 months and so far things are going swimmingly.  We communicate well, he's met my family, and we took an awesome trip to Hawaii this winter.  He's smart, loving, supportive, and awesome in bed!  He's just the kind of person who I can see myself making a life with.  

About a month ago, I met up with a man I dated in my turbulent 20s (no funny business, just a beer and a catch-up).  He and I had a strong emotional/physical connection but he ultimately broke my heart.  I've never blamed him for how things worked out and I've always had fond feelings for him but I truly thought I was over it.  I hadn't even seen him in 5 years before last month! 

Ever since then, I've been thinking about my ex frighteningly often.  I think about how unique he is, so creative and vibrant.  Sure, he was flaky as hell but he was always introducing me to cool movies or taking me to events that would normally be outside my milieu.  I've been comparing my boyfriend with my ex in a negative way, like "Oh, my ex wouldn't be making me listen to this same Arcade Fire Pandora station for weeks at a time".  Really superficial stuff, but stuff that kind of matters to me all the same.  I fantasize about what it would be like to date my ex again, forgetting about all the times he made me feel worthless and insecure. 

To be clear, I'm not actually considering making a move on my ex.  He's in a new, complicated relationship (ha, the only kind he has) with a pretty, young thing.  I'm just worried that these feelings are a signal that my boyfriend is not the one for me.  On the other hand, maybe my meeting with my ex just unearthed some baggage that I need to deal with.  

Help, this isn't fair to my boyfriend...he deserves better!!
<bot>: I'm in a happy relationship but am having recurrent thoughts about an ex-boyfriend which is causing me to wonder where my heart belongs.
