Urgent ... Engagement Date Is Coming Close

Me and my GF have been in an LDR for about 7 months. We've only spent a week physically close with each other.
Now I'm about to fly next week to her place and then go for a 2 day stay at a private villa next to a beach. We are supposed to get engaged next time.
She's a really cool girl but we only seem to connect when it comes to sex. We share our fantasies openly and she's been keen on trying to arrange a threesome for me (She's had 3somes, 4somes and an orgy before) and is open to couples sex, orgy ... anything.
I keep trying to think that I should get in a state to tell her that I'm not feeling it but before I can say anything, she starts talking about sex stuff and I get carried away with all the sexting.
Any time we talk about sex we connect brilliantly cause she is open about everything she will do .... But in every other way it seems dull. I dont mean to sound arrogant but sometimes I feel that she couldnt even hang out with a group of my friends and chill cause she isnt exactly smart enough and her english isnt that good. And I know I sound like I got a 20ft carrot up my ass, by she isnt very sophisticated with her communication as well. We dont seem to connect on an intellectual level.
But every time I think about all this, she talks about sexual fantasies and I get carried away

Someone please help me .... I know I'm gonna come across as a bad guy in the end. But I dont want us to regret this marriage later

 

umm, don't get engaged.

 

Haha to the post above me. Um, yea..theres really not much else to say and I think you already know this and just wanted to hear someone else say it.

 

I would also suggest that you get a refund on that ticket.

 

I wish I could still give hipforums karma. You just saved this gentleman an unhappy marriage.

 

The sex soon won't be enough....you will get tired of her if you don't connect on other levels.
