the other day i was in my first date with this hb and my phone rang and it was another girl ive been gaming, i didn´t know whether to answer or not, anyway i didn´t and i told her it wasn´t important. I tought it would have been rude if started talking to another girl infront of my date, but on the other hand it may build some good jealousy.

Soooo, my question is: should i answer the phone if im on a date? what if my mom is calling or some male friend of mine?

You're alpha. Do what you want. Your date can sit there and stare at her fingernail polish until your done talking on your phone.

but what if it becomes a 5 min phone conversation?

if a were a girl and a guy who invited me on a date starts talking for 5 minutes on his phone i would feel like shit and pretty unrespected.

On the other hand, if i answer and say something like call me later im busy right now, it would make her think that she is important to me, when thats not the case yet...

I think the best thing to do is simply to put the phone on silence, and if she responds to some text she is getting from someone else for instance you may say you look like those girls who cant stay away from the phone

Ok, first of all, getting calls makes you seem important. So don't be afraid to let her know you are getting calls. You can even answer them in front of her. Remember, you don't have to tell her who it is and you can also constrain the words you use while on the call so it doesn't reveal too much. You can even DHV yourself to the person calling you and be like "Hey, I'm actually on a DATE right now, can I call you back later?"

It may not be the best policy to let her know another girl is calling you, because that might make you seem like a player or cheater. So be careful with that. What I would recommend would be to to answer the call, do the normal "hey, what's up, let me call you back later" thing, so that your date has no idea who it was. If she asks, or even if she doesn't, just tell her that it was one of your buddies calling to see if you wanted to go out to a bar/club/party later on. That makes you seem like you are an important person in a large social circle of some sort.
