Seriously? 2 ex's in a day and 4 ex's in last month?

Today I met the patological-liar (God he looks terrible) and the guy I've been kinda in-love with for quite a long time. (While we both were married to other people.) Let's just say he's as cute as he used to be.

And just few weeks ago a college love interest (been dating for a month) found me on fb, as well as a guy that i had to start avoiding because he wouldn't get over me, let's just say he still didn't got over me, after 12 years (YIKES! O_o)

The problem is with the cute guy. He used to be my friend and not only lover but there was some kind of a sparking between us. I gave him my phone number, I'd like to get back in touch because I like him but I am afraid that the spark might come back. I don't want anyone else but my SO, he's the love of my life, but you know... sometimes you shouln'd even create an oportunity to do something you will regret. I am afraid that even though we have kids now and are strong into relationship it is creating oportunity.
