First talk with girl, to see if she is the one that WANTS to make me jealous. Now, all You wonder: WHAT???!
- For all of you, males, girls often want to make their boy jealous just to see IF THEY CARE! That is the thing in 70% of that cases.
That does NOT mean that there is NO reason to be. Always make a TRIPLE check. First with her, find out who is HIM - with no MANIC behavior, then go to HIM, talk see if "story" matches 100% (i recommend a drink, some alcohol while talking, HE will open up more) - and then make the right decision ; is there a reason to be "jealous" or NOT ? It is a blade with two sides (I am not sure if I expressed myself good in this phrase, Serbian is my native - not English, but I try hard) and You all should be careful - including FEMALES that, either have a goal or ... doing "their thing" behind back of someone who gave you hart, trust, beautiful moments, dedication, etc...
For girls: Is one night adventure, that eventually end up with sex, is worth of ruing "a house thats build over months, years.." ? Flirt, go out, dance - but have limits, and think twice when You are under influence of anything while flirting - what and where that conversation is going.
I hope I gave an good answer.
