I think that it’s more than just his “desire” for a perfect proposal. The way he keeps the ring out to taunt you is just ridiculous. When he knows you let the ring stay in plain sight but are almost afraid to touch it, when it’s supposed to be yours, where he can watch you “squirm” so to speak — this just tells him you have given all the power to him as you wait passively for him to get around to you. Sounds like he gets off on that now, having control of you. That’s not a good attribute for a potential husband. There is a reason why he is not proposing.
What if you felt like an equal partner and put the ring on with confidence, acting like you have a right to it, because you do since it’s supposed to be yours. This would show him you are no longer a little victim to his game and that you have a strong, confident will of your own instead of being treated as his puppet. He could see you with a new respect, or it could be a dealbreaker. What a kick it would be though if he were just waiting to see if you would assume your role, to take what’s yours and do just that. However if he pouts and throws a tantrum like a child about it, then it’s more about having control of you than the desire to make you his wife.
When girlfriends know they are the girlfriends, are loved, and are secure in that, they act like they belong there; whereas others, unsure of their standing, tip-toe on eggshells and come across as though they don’t really have the right to be there. That is what I’m talking about, brought on by the way the man is acting, vague and toying. By having the ring sitting there, as no secret, right in front of you…yet you now feeling less and less like you are entitled to it, could convey to him some insecurity about who you are in this relationship, the way it comes across. That gives him the control and power. This guessing game behavior and withholding tactic of his will have a way of eroding your own worth and tend to make you less and less secure. Hope I’m explaining it the way I’m feeling it for you. I am so sorry you are going through this.
Now granted, if he is really, really wanting his own major proposal moment, this won’t be it and he may feel short-changed. You have to consider that. But to me he had plenty of opportunities to have a romantic proposal—including the moment you found the ring—but didn’t take them. The longer it goes on, the less inclined he may be. Plans not executed tend to fizzle sometimes and the momentum is lost. Because he didn’t act on it yet, this naturally would make you feel in limbo, and that is never a happy place to be.
That said though, people do get ready on their own schedule, so it has to be what is comfortable and feels right. I’m not saying to do one thing over the other. I’m just throwing some thoughts out there. But don’t let yourself start to doubt yourself or damage your self-esteem.
