<human>: Can you give me a shortened version of the text?

So today is my gf and I's anniversary. Unfortunately, it's also the only day I'll be able to see a friend that's in town for the week along with a lot of other friends.

I normally wouldnt even imagine shirking the anniversary for this, but there's two factors in play. The first is that I've gotten together with my gf these past two days (a big thing in our relationship, since we don't see each other much), so it's not like I'm trying to avoid her or anything. The other factor is that she and I could potentially reschedule what we're doing today for another day this week, whereas obviously can't reschedule hanging with the friend (won't be back for many months or something). 

I understand that this is dangerous waters trying to talk about rescheduling when to celebrate a two year anniversary, especially the day of, so I mostly just want to know if it's even worth trying.
<bot>: Friend's last day in town, today, is same day of two year anniversary with my gf. Want to know if it would be dangerous to try to reschedule two year anniversary activities for other day this week.
