Can a Scorpio sex buddy turn into a boyfriend? ?

[Loredana L]

I'm a Leo women, in a relationship for 3 years with a guy. About one year ago I begun flirting with one of his not so close male friend that is Scorpio. Recently the flirt turned into an affair. We basically have sex once a week.
What would be the chances for this affair to turn into a relationship. Do you think that he's just having fun or does he have more serious intentions? I can't really tell.

He might want a relationship, you can't tell with some guys, but I doubt it can turn into a relationship.

Bang him 3 times a week and see if he starts to resist you

Tell him you love him...then you'll know for sure.
