It's H's birthday this month. What do I do?

When H first left he gave me both Christmas and birthday gifts. I gave him a 'peace plant' once, the first Christmas. He had the card on display for quite a while after.

I have given him nothing since. Last year on his birthday we even had an argument. On my birthday earlier this year he came to visit and sent a text but no card or gift.

Suggestions? Stick with nothing? Something personal? for his house? an invitation? something fun?
