In my opinion, and more so under the circumstances of your current relationship, your proposed approach is likely to be experienced as both deeper, and more genuine love than by way the alternative road. She already knows how much you would wish to hold her, and she also knows now that your love for her is well beyond any love you may have for yourself. Sleeping in the same bed is the ultimate test for how genuine be ones love under these circumstances, so your plan is absolutely on the mark. Every other uncaring guy would try and jump on top of her, so don`t go there even in love. Actions are everything, and especially where they concern self denial to meet the others needs. This is the ultimate test for your emotions, but you sound very well prepared, and get through it and I believe that it shall prove very therapeutic in both the short and longer term. It`s an exercise in emotional control, and thus in being both stronger and healthier emotionally, perhaps eventually able to happily deal where others cannot go. Think prospective, think "only" the very ultimate friendship (imagine that she is under age), not love.
My lodger has just tried to stitch me up to the tune of £1000 with false information. She is genuinely sorry for the circumstances of her mind which took her there, and so the incident is forgotten, and our friendship is untainted. Meanwhile, I am now aware of what she can do.
