I think you are in danger of 'over thinking' this. Don't worry you're not the only one that does that. I do that sometimes. Meeting for coffee is just that. You don't need to 'disclose' anything more than is on your profile before you meet. If first impressions are OK and you feel comfortable chatting and work comes up then obviously you don't lie but put things in as favourable a light as you can. Bit like a job interview really. None of those things should put someone who is genuinely interested in you, off.
As regards what happened in previous relationships you learn from them, draw a line under them and move on. Everytime is different . Things that happened before won't necessarily happen again. Hope it goes well. Let us know how it goes.
