I think u both need to sit down and talk about how u feel. Tell her its not jealousy, and im pretty sure if it was the other way round she would feel the same. I would not be able to take ny husband with other frends like that. Don't get me wrong its not the hanging out thats the worst part but the scenarios u have stated can only happen when there is some sort of connection, this does not have to be said by words but actions too tell a bigger picture. Just imagin you with a gal who you have no feelins towards, and that woman tried to make a pass, you would be able to move out the way pretty quickly and if that was me, i think that would affect the frendship i had with that other person, cos no doubt this other guy knew the gal is engaged? Im not sayins he def is in the wrong cos people have different types of frendships but i just think they both need to re-evaluate their frendship and esp once your married. U need and must discuss these issues before u get married, cos no doubt it will only get worse if they stay undressed. I prayfor u and that u both sort it out,so u can both live in harmony and raise your kids the right way. inshAllah
