Can't tell where I am at with my ex and if I should wish them Happy Birthday?

[unsureofwhatsay]

So my ex of 9 months and I broke up about around 3 months ago and have had very little contact since. He initiated the breakup, but it was mutual for the most part - I agreed that it was for the best. When we broke up he said he still wanted to be friends (I wasn't the one to bring that up) but while we say hi when we run into each other, that's basically it. He hasn't really made an effort to back up what he proposed. While I still care about him and cherish the relationship (and friendship within that) that we once had, I've moved on for the most part and have met other people (nothing serious), and I am honestly not interested in ever dating him again. I wouldn't mind reconciling and maybe forming some sort of a friendship eventually.

 

His birthday is coming up in a couple weeks and I can't decide if I should wish him a happy birthday or not. I'd like to do it as a means showing him that I would like to be friendly and I don't want to appear rude completely ignoring his birthday since we didn't end things in a bad way. However, I am afraid of giving him the wrong impression and making it look like I want to get back with him or something since we haven't actually talked in so long. I feel like he also gets the upper hand in it all if I'm the one to reach out before him. I know my ego will be a little bruised if I get back a very short response.

 

At this point I have no idea where he is at when it comes to us and the breakup and what he wants out of it. It's frustrating to hear that he wanted to be friends and hasn't backed that up. I understand that it is a healing process and maybe I have gotten through it faster than he has or maybe he has changed his mind. The situation is also difficult because we see each other every so often because we work in the same office complex and our town isn't super huge and we have some mutual friends.

 

What do you all think? Is a facebook wall post or text appropriate or should I just let it go for now and give it time?
