<human>: Ok, so I have a group of friends from university, two of whom (lets call 'em Jimmy [25M] and Alicia[25F]) had a pretty serious relationship for a while (2/12 years), then broke up amicably. We all left uni 3 years ago, but still meet up a few times a year. Jimmy and Alicia are somewhat cool with each other, they're still pretty friendly, although won't choose to each see each other outside of the friendship group.

However, Jimmy has a new girlfriend, Lana [23F], (they've now been together for over a year) who's intimidated by Alicia and doesn't want to be around when Alicia's there. It's a shame because Alicia's one of my long time friends, and Lana's also a super cool girl who I'd like to get to know better. Basically, they're both awesome people, and they have got on well in the past. However, Lana's still not comfortable when Alicia's around. Lana gets pretty anxious over social things, and Jimmy and Alicia's relationship was a pretty big deal in our friendship group, were planning moving in together, marriage, etc which I guess makes it even more intimidating for Lana. Also, the rest of the friendship group isn't entirely helpful for putting her at ease when Alicia's visiting, saying things like "Oh my god isn't it going to be SUPER WEIRD seeing Alicia??" etcetc.

I'd really love for us to all be able to meet up easily, and for Lana to be at ease if Alicia's going to be around- I'm basically looking for some suggestions from y'all to help Lana feel more comfortable with the whole situation.

Can you give me a shortened version of the text?
<bot>: Friend's current gf is uncomfortable with meeting up with his ex in a very close friendship group, need suggestions on how to help make her feel more at ease.
