DP and I have been together for about 3 years. No DC. He has a hobby, takes it quite seriously, goes to national and international events/competitions a few times a year.
I know that the last person he was involved with before me was a particular girl who does the same hobby and who he used to see sometimes at these international events. They got together at one of them, and met up again once more after that. But because they live in different countries, it never really went anywhere. This was a couple of months before DP and I met and got together.
(BTW I worked that all out from bits of what DP said plus other snippets of info from friends/FB. Originally when DP mentioned to me early on how he had visited this girl, he told me it had been a visit to a "friend", I later worked out it was actually more of a booty trip)
I knew that they still chatted on facebook over the years, particularly about the hobby, and I thought that was fair enough. DP was fairly open about it.
Not too long ago he left his FB private message page open on his laptop. I noticed a conversation thread with this girl from a while back, and the first line (visible) was enough to make me feel insecure and suspicious. I opened the whole conversation. It was a bit soppy on both sides, reminiscing about the "special, amazing" time they had together - but clearly the time before DP and I met. I didn't like it, but then again there was nothing actually there like "I wish we could do it again" or anything. So I put it out of my mind, and I felt guilty for having opened the thread.
Anyway, now DP has again left his laptop open on the central message page thing, and there is another, much newer conversation thread with this girl. The first line references an international event for this hobby that is coming up soon and the fact that they will both be going. I am dying to open the rest of the conversation, but I haven't.
But I feel uneasy suddenly. Like it would be so easy for him to do something with her while he is there, completely away from me and anyone I know. I know he loves me and wants to be with me, but I think that part of him wouldn't think it was that wrong to sleep with someone as a one off if I never found out, in a context completely removed from our day to day life.
And this girl is stunningly beautiful going from her FB photos. And they obviously see themselves as having had a special connection that was basically only thwarted by geography, not incompatibility.
I am dying to open this message thread, to see if there is anything that might confirm my half-formed suspicions about what they might both be thinking of doing. But I know that I shouldn't and that it would be wrong. And where would it end if I find nothing? Should I talk to DP about what I'm feeling? Or should I do nothing and am I being ridiculously disrespectful of his privacy and getting worked up over nothing?
Argh, somebody advise me! WWYD?
