Thanks guys for all your advice, some of the comments and suggestions are what i was also thinking. My point was not just having relationship and losing virginity, my point was having an affair sexual as well as love whatever you say and trying to hide it. Keeping one person as a backup and kicking his ass when you get another probably the better. I didn't like that oppertunistic behavior.
 Knowing that you guys will say thisis america it is not a big deal i already told i am grown up in Nepal and i still belive it is not completely gone that wild. Everythingis measured by social norms, somebody who can take the risk of social norms and lies is not trustworthy, that was my real concern. And belive me the difference between your imagination and rality always hurts you. If you were clear and you accept it, it isokey this is your fault but being lied and betrayed is something you could have avoided. I caompare this to the behavior of Wolf.
Thanks any way. This is not just my problem, it happens to many nepalese but some can accept it some live hard with it and some quit the relationship. I was thinking
