Please be gentle with me, I really don't know if I'm being fair here. I'll try to keep to the relevant stuff, but think it might be a long one...
I have two friends, let's call them Peter and Jane. Peter is the son of a very close family friend. He is a couple of years younger than me and we've grown up together, albeit at a distance as they live the thee side of the country. He is, to all intents and purposes, family.
Jane is one of my school friends. Weber never been the closest of our group, but she is a good friend.
About 2 years ago, Jane started on a grad scheme. Peter studied the same subject at uni, and back in the summer got offered a place on the same scheme. I put them in touch so he could ask Jane some questions about the scheme etc. he took the job and moved here in September. Since then they have worked together on some projects and became good friends.
Peter had a girlfriend from Ireland at uni, who had to move back for various reasons. TBH, their relationship was never great, at least not from our POV.
Peter knew nobody apart from me and my DP, and just about knew Jane when he moved here. We've been introducing him to various friends. I invited him to our traditional pre-Christmas piss up get together with my school friends (including Jane).
On the night it all came out that Peter and Jane had slept together. We were all very drunk and so it was a bit of a mess. Peter was still with Irish girlfriend at this point. Jane basically declared her love for him at this point, though she was really quite pissed. They then proceeded to spend the rest of the night dancing very closely and snogging each other's faces off right in front of me, to the extent that Jane seemed to be purposefully following me around when I tried to move away.
Peter has since broken up with his girlfriend, but it all got a bit messy and he was really quite upset by it (clearly not as upset as his girlfriend, who was devastated. He readily accepts that he's been a total bastard in cheating on her).
Since then Peter and Jane have spent pretty much every second together. He confided to me the other day that he has no idea how it will go, but is just going along with it because it's making him happy right now.
Now of course, I want them both to be happy. But I am really sad and worried that one or both of them is going to get hurt. Jane has been going through a really tough time lately, and was recently really hurt when someone else she was seeing told her he didn't want a proper relationship. She had a bit of a history for having casual relationships in which she then gets hurt when her much stronger feelings aren't reciprocated.
I also worry that this is becoming. A bit all-consuming for them, and that they're isolating themselves in this little pocket of life they've created for themselves. They're working, sleeping and practically living together. If it all goes tits up then that's everything, especially for Peter who still has very few other friends here.
I absolutely do not see a future for them. They are incredibly different people with different outlooks on life. I worry that they were both a bit vulnerable and their friendship became very intense.
How do I stay a good friend to both of them? They both know I'm struggling with it a bit, but are quite flaunting of being together. I arranged to meet up with Peter for a coffee, and when I got there Jane was there too. I went round to see Jane and a friend staying with her, and she invited him along.
AIBU to want to see each of them without the other? Or is that unfair?
Also, each of them keep trying to confide in me about the situation. AIBU to say I don't want to keep being dragged into it?
If they end up together and in love, fine, I'll accept that and get used to it, but as it is they are basically just sleeping together and I don't want to know!
And finally, AIBU to expect them to not be all over each other when I'm around? Even other friends who'd never met Peter before were commenting is was a bit grim
