er i disagree with the last poster...
relationships don't have to be about playing games, you could just trust your own feelings and do something genuine to express yourself
if you wanna call someone, call them
if you are unsure or feel uncomfortable, don't call.
no energy wasted second guessing another person's feelings, which you can never genuinely guess anyway especially since you don't know them well.
it may or may not work out - but if you are looking for someone to spend time with isn't it better to find the ones who are capable of responding to a genuine call with an honest and genuine reply?
this is true in all relationships - romantic, friendship, business, family IMHO
I've only been out of a relationship for a few months in the last 20 years & I never had to play weird phonecall games to make a genuine connection with another human being
hope this helps
be yourself - you are just fine :-)
