<human>: We were best friends over 4 years and dated over 3 years and just broke up before she moved for grad school. But things ended in a weird way, and it's only been 5 days since I last texted her. Her birthday is the 28th and was wondering if I should wish my ex happy birthday and what everyone thinks? Break no contact? It's a complicated story but the main reason I got myself here is from being too needy and not giving her enough space. Shes an introvert and I really smothered her, they need to feel they can get away when they need to and not feel bad about it and I was like a ball and chain for her emotionally. I don't want her to think I'll keep being that guy.

Can you condense the text into three sentences or less?
<bot>: womdering if i should wish my ex happy birthday. Any thoughts? Maybe say happy birthday with small apology regarding what I've realized, then resume no contact? Say nothing?
