<human>: Can you provide a brief rundown of the text in within 3 sentences?

I am still in love with my ex even though she has no feelings for me whatsoever. She explicitly told me that 5 months ago when we broke up, we recently exchanged a few texts (it was her birthday). She told me that she's become a workaholic since then, and I want to tell her she can talk to me/if she feels lonely/has no one to talk to. What's the best way to phrase it without offending her or making me look like I want her?

I accept that she may never like me again, and that I have been and will have to continue to date other women but until she has a ring on a finger I feel I will always want her or fantasize a scenario where we could be together again.
<bot>: What sort of message can I send to my ex to tell her I still care about her without looking clingy or needy?
