If you have reservations you shouldn't do it. Until you can accept his devotion for what it is, if you ignore your heart and force yourself to do something you obviously aren't ready to do you'll regret it and possibly blame him for pressuring you into it. Do things in your own time in your own way.
The best advise I've ever gotten was, "if you have to ask, you already know the right answer". Besides, if the only love you feel for him makes you feel like "extra closet space" you have other issues that need to be addressed before you're ready to be with anyone. Unless of course it's your subconscious telling you that he's not the one.
Listen to yourself. Do what is right for you, not someone else and you'll never go wrong.
First off if it is what you truly want to do them do it! Take into consideration though that your reservations are for something and should not be overlooked or taken too lightly. It may just be that natural fear of commitment response or there is another reason that only you can answer.
I do think if you are that passionate about him, that you should, but for yourself you need to answer that question. Hope this helps!
I can only go from my own experience, but I did the exact same thing! I have known him for 25 years now, and we have been married for 22. If you'd to use that as a real-life model, the answer is no!
You are not making a mistake.
I don't think you are making a mistake by moving in with him if it's what your really want to do, and if you feel you have a healthy relationship that is going in the direction YOU want it to. It sounds like you are worried that your needs won't be met. If you are paying half of the rent, then taking up closet space isn't a big deal, I'm sure he will be grateful.
On the other hand if you are just moving in and aren't paying for your half of the rent or compensating with housekeeping and bills or some sort of equal agreement then taking up his space will bother you. If he says he wants you there then believe it. If you are paying your way it's technically your space too, so own it.
If you still don't think you will feel comfortable, then don't move in, perhaps you should wait until you're married anyway. I think that if you want this relationship to work maybe you should say something like," hey why don't we clean out the closet so I can have some space in there". If you want something you have to ask for it.
Don't worry about being on the lease, he obviously wants you to be close to him, and besides like you said, you can always go home to Mom and Dad if it doesn't work. Think positive though, it will be more likely to work if you do. And ask for what you want, what's the worst that can happen, he'll say." no, I don't want to share the closet.
" Maybe you can store some of his unused stuff in Mom and Dad's garage:).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
