Rapport Dictionary Definition

personally I would find it a big problem. I dont want to sound like I dont trust a girl or woman I am with but I dont think that a husband should be spending time with other women alone without the other spouse women also. Even if they arent doing anything wrong its still not right to go without you. To me is seems like he spends way more time with them than your family which is absolutely wrong. I think you should have a talk with him and question it all and tell him you dont appreciate it that you dont go along and that he shouldnt be with her and the kids alone. Personally I think there may be sumthing goin on there but that is just me And also hes way too old to be hanging around a 13 year old child that is not his including emailing. I wouldnt tolerate it at all but that is just me I hope I helped some I hope there is nothing behind it at all and I hope you can figure it all out and Good Luck!!!
