Tigge; First of all

you need it. I am sorry you were disappointed in your BF's lack of proposal at Disney. I think we all want that extra special proposal to happen. I have a few things I wish to add to this. These are my opinion and in no way are facts or insults to anyone. Some of what you say about your boyfriend concern me.
* He had you tentatively agree to a marriage before you left? Are there issues?
* He didn't get the babysitter, now on its own, I would think that if he wants some alone time, then he should do the arranging, but, as a matter of compromise you could have just as easily done the same. I do think it is a part of a much bigger picture though and you have your reasons for wanting him to follow through.
* You and he had accepted an invitation to a party. Now he wants you to cancel for some alone time? That is odd. Maybe from my history of being a victim of domestic violence I see things in a negative skew, but, why can't he work around that date? From my calendar, it isn't Valentine's Day or anything romantic, just an arbitrary date.
* When you didn't agree to cancel for him, he hasn't spoken to you in five days. Now, alarm bells are going off in my head. It is one thing to be saddened or disappointed by a change of plans (as you were at Disney) but it is quite another to give someone they claim to love the silent treatment. Is there any guarantee that he is planning a romantic setting to ask you to marry him? And what if he doesn't? Then what?
* I honestly think you need to question why it is you want to spend your life with this man. Does he make you happy? Does he treat you with love and respect? Does he put your needs ahead of his own? Does he do that for your child? If not, then you should consider waiting on accepting any proposal from him.
Never ever settle for someone that doesn't make you feel like you are the most amazing person in the world 99.999% of the time. We all deserve that.
