Hi, long story short:
we met when he had a LDR. We fell in love. He broke up with her to be with me.
Then he broke up with me, saying we weren't happy together.
He got back with his LDR gf.
After months of NC, he emailed me to say sorry, and that he's with his ex gf now,
and if I'm ok with it, we can rebuild our friendship.
I replied him with gratitude and tho I didn't ask him anything, he replied with an email talking about himself and asking questions about me. I didn't reply again.
Then, recently I saw him again and he invited me to this BBQ (him and his friends' BBQ).
The first time I said I had plans for dinner but he laughed and said the BBQ is for lunch.
Then I just focused on talking to other people, but then he brought it up again (He invited me to the BBQ again).
Why is he doing these things? I barely paid attention to him and I have been quite cold to him in our interactions.
