<human>: Can you summarize the given text in a few sentences?

So my ex-boyfriend and I (both 22) broke up about 10 months ago. We had a rather clean break at the time though he was very upset that I ended it, but we initially agreed to still be friends. A few months after, he called me drunkenly saying he still had feelings for me, and then promptly unfriended me on Facebook. We haven't spoken in about 6 months.

His birthday is coming up and I would like to say something to him, as I do care about him (we spent 2 years together). Is this inappropriate? He clearly cut me out of his life and I want to be respectful of that. I also am now in a new relationship and very happy so I don't want to convey the wrong message - I just want to make sure he's doing well.

What do I do?
<bot>: My ex (22M) cut me out of his life after I broke up with him last year. Is it appropriate to reach out on his birthday and see how he's doing?
