Cancer girl found long lost pisces...HELP...

So Last time i posted..i was in a "situation" with a pisces that had a girlfriend...Well i felt really bad and ended things with him and we are now JUST friends...NOW..Ive been single since feb. and have been enjoying this time to chill by myself..A couple days ago, i checked my email only to discover a message from an old friend (pisces)... We've always had good chemistry but time was never on our side...when we first met he had a girlfriend (lol coincedence??) ..then last year i ran into him an we exhanged numbers and talked but i had a boyfriend (libra)..NOW here we are again.. we're both single and met up for dinner. I cant lie it's "something" about him...we have been together almost everyday since getting back in contact and my mind is swirling!!! lol..I want to take things slow but i cant stop thinking about him..i dont want to "drown" him with my emotions lol..He says he feel the same exact way and that he also wants to take it slow but i jus dont kno what to do myself...when i think about him i blush uncontrollably...He's usually shy but around me he's fully engaged in our conversations and it's crazy...i feel crazy lol.. what can we do to slow ourselves down before we sink of emotion?? and is this feeling juz for now or could it be what ive been looking for?? His birthdate is march 7..
