<human>: My boyfriend Will and I have dated for 1 year. Before that, he dated Emma for 2 years. Will met Emma through his friend who shared an apartment with Emma at college. Because of this, it meant that Emma is also good friends with all of Will's friends. Emma and Will were each others first serious relationship. Plus, she's one of those cool girls who just seems really fun, loads of friends etc. So I was pretty intimidated by her.

I met Will's friends (minus Emma) and they were all nice to me. Although it was a bit weird. I really felt like the outsider coming into a group of people who all love Will's ex. Especially because some of them knew Emma before they met Will. Mostly the guys just hang out and have guys nights where girls aren't invited, so actually I didn't have to see Emma and neither did Will. Emma is now dating someone else anyway, who I met before her and he was nice to me.

Anyway I met Emma shortly afterwards, just briefly, and she was super nice to me. We met again at a party a couple months later and got a bit drunk and chatted for ages. She was really friendly and welcoming to me. Anyway, we became friends on facebook and basically since then we have had a weird thing of liking each other's stuff and making little comments etc e.g. "cute photo". She initiated it, I would be too nervous to do that! It seems like she's really making a big effort. I don't really know how to interpret it to be honest. Only one other person in the group has done anything like this, and I've spent a lot more time with him, and he just occasionally likes something.

Anyway Will also thinks Emma is making a big effort, and I don't know how to interpret it or how to respond (apart from liking stuff on facebook... not at all superficial haha). Just looking for some outside opinions!

Could you distill the essence of the text into 1-3 sentences?
