Fish swims back?

Hot and heavy 4 month fling ... It's been about a year since I've seen this Pisces guy. (that I was really into) We've randomly connected a few times, but haven't seen one another. I heard he was dating someone seriously. We met shorlty after terrible respective breakups and didn't want to "jump into something." (this fish gives me a terrible case of the giggles! waters are running deep over here, but I had a big emotional mess to clean up when I met this guy)

We connect recently. (he's still got that someone serious) He has something to give me. I say I want it hand delivered. He says, you got it.

My questions:

Are Pisces men known for exploring the options while in a relationship?
Do Pisces men tend to go back to people?

perhaps he's just being polite ... ?

yeah, that's the other issue ... but that was more of my own personal thing - not so sign related.

I agree that I wouldn't want someone who cheated, etc. But, it's human nature to check out the grass on the other side of the fence ... When we disconnected a year ago - we just didn't want to rebound into one another because the feelings were so strong.

I'm seeing people, it's not like I'm sitting around waiting for him .. but, darn it - I wanna be paying attentiong if he's swimming back ...

I had another Pisces ex, who I believe, checked out his options prior to our break-up(after 5 years) ... maybe that's common?

Then when he is done with you, he will check out his options again perhaps?
