So my friend has been in a relationship with someone she loves for a while now but since I've been out of state I haven't been able to hang out with her until the holidays. But now that I've visited, it has always been when her girlfriend is around and they are always breaking away to talk by themselves and etc. And while I'm totally fine and happy that she's with someone she likes, sometimes I find myself feeling kinda awkward? I end up wondering if I should really just be more independent and wander off so they can be cute and couple-y but at the same time, they see each other all the time and I'm literally only going to be around for like... 4 days? This is just something I don't have a lot of experience in. Any idea what I should be doing? Cooing over them? Calling them gross PDA-ers? Ignore it all? Run away?
