A possible new relationship, is this healthy...? PLEASE READ- I need advice/input!!!

So this is my question/situation...

I have recently (about a month ago) met a really nice guy. He has a unique past of his own & we can identify w/each other on certain levels, i.e. both having crazy moms & a troubled family life while growing up, feeling alone, etc. He has been very sweet to me & I've really opened up to him. See when we first started talking it was almost 1 year to the date from when I was gang raped by a guy I was on a date with & 3 of his friends. So I was having a real hard time w/that & this guy proved to be a great source of support for me to open up to. But the thing is I don't trust myself, I am scared all of the time, I long to be protected & cared for- & he knows that. I do believe he really wants to help me & be there for me. But I'm worried if I enter into some sort of a relationship w/him where I look to him for protection & safety & want him to take care of me that it will only further fuel my inability to take care of myself. It's this weird paradox I'm in. I feel he is very nice & caring & he wants to take care of me & treat me well. He is dominant though, which I find comforting because I am pretty submissive in nature. Still I do not want to become dependent on him. I want so desperately to feel safe & cared for! Maybe I am incapable of taking care of & protecting myself. Perhaps this is the best situation for me, to have a dominant male figure in my life that truly does have my best interests in mind. But how nice it would be to once again feel confident & in control of my own life... He says he wants me to be his, belong to him. He will help me work through this & take care of me. HE knows what I've gone through & always tells me I didn't deserve that, that I have so much more to offer than sex, that I deserve to be taken care of & cherished. He doesn't even want to have sex until after marriage, so I know he won't be using me for that. I just don't know if I'm giving up on myself or selling myself short to be basing my sense of safety & confidence in the protection & reassurance of a man???

Is this a healthy relationship? Do you all think this sort of dynamic -me depending on a man to protect & take care of me, even if he is very sincere & truly wants me to be happy- will be detrimental to my overall well being & recovery? I don't want to limit myself or be stuck in a bad situation. I also don't want to pass up a good thing & the chance to be w/someone that actually cares & recognizes my worth as a human being. Please help- any advice or input would be ever so greatly appreciated. Maybe some of you have experienced similar arrangements or are in these types of relationships now. I would love to hear other peoples experiences! Thanks so much!!!
