I know it will hurt but you need to dump him if that is how he feels. It will save you heart ache in the long run. Trust me he doesn't love you if he is willing to be with another girl at the same time.
I'm a guy and could never fathom being physical with another girl if I was in love with a girl. It would hurt me because I know it would hurt the one I truly love. Personally I think he doesn't deserve you and you should move on (I hate to be the bearer of bad news).
Its a HUGE red flag to me that he wants another girl other than you so I personally don't think the relationship can last. But if you really like/love him and want the relationship to stay intact then you need to tell him you don't want another girl in the relationship and if he won't understand then he doesn't deserve you. At least that way your conscience is clear because you did everything you could to keep the relationship intact and won't wonder down the road if you could have made it work.
Find another guy who will treat you right if it doesn't work out. There are many good guys out there just waiting for a girl like you:). Good luck and I hope everything works out and I'm sorry if it doesn't.
It's a fantasy of almost every guy and at least he's being honest with you. It doesn't mean the relationship is destined for failure at this point but I believe you learned a valuable lesson from your parents. I'm sure there are those who will argue with me but I believe it's a huge mistake to go that route and is surely not indicative of a strong healthy relationship for those who do.
He wants you to be a part of it so it would seem he still wants you. You may want to ask him if he still would like to go through with it if it resulted in you two eventually breaking up. If he chooses the fantasy over the real thing that he already has then at least you know where you stand and can base your decision on that information.
Ultimately my advice would be to tell him "You get me and if that's not enough you don't get me".
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
