I have been with DP for 6 months, lived together for 2 months.
Before we met he had arranged to go on a 2 week holiday with a female 'friend' of his, according to him she is his best friend etc
He told me for the first few months that nothing had ever happened with them etc, he didn't find he attractive, just mates but then it came out when he was drunk that they had slept together once (so he says) in the past.
Before I knew of the sexual history I thought I would be ok with the holiday (they are sharing a room) as they had been friends a while and it wasn't like there was any spark with them.... but now I know they obviously like each other enough to sleep together I feel differently.
I think I will spend the fortnight paranoid, insecure and whatever he says happened when he gets home I wont believe him. Her and I don't really know each other and haven't really gotten along with her the few times we've met, mainly because she hangs all over dp, texts him alot and generally asks him stupid questions like "do you think i'm pretty, will anyone ever want me?"
He has lied to me about her before, saying that his mate had invited her on a night out and when I asked his mate if she was coming he didn't know what I was on about and it turned out he had secretly invited her but didn't want me to know. He said he had missed her lately and had just wanted to see her. Which is fine, its the lying that bothers me.
The holiday is at the end of the week, he says now he doesn't want to go because he will miss me but also wont lose the £1500 he has paid for it. I've heard him telling her he can't wait to go. Also he deletes her text messages and although i've not looked through his phone i've seen her name on his inbox list and watched him check the boxes to delete just hers.
I just feel crap about it.
