Dear Dáithí: My girlfriend thinks I’m planning to propose...but, I'm not
'Do I just go ahead and buy the set I planned on getting her and be very clear that it's NOT an engagement ring?'
What we really need to do is manage this, so she’s not expecting a proposal from you. When she finds out that there is no proposal, she will be disappointed, even if she never believed there was a proposal on the cards.
Be honest with her and tell her that it will happen, if she wants, someday.
