I have experienced a lot of grief and sadness in my life to now . He is like a life saver
From your last post OP it reads like you are in love with the idea of what this man represents, you want to be love and adored, cherished by someone special and for the grief and sadness of the past to fade. I would guess that you are impressed by the fact he has his life sorted as such (home, car, good job, supportive family and friends) you describe him as interesting while you see yourself as not and that is your problem. You are starting this relationship with him from the starting point that he is "better" than you and that kind of start will never have a successful conclusion.
I too had a bad start in life, lots of neglect and abuse and felt "less than" and in a serious relationship did what you do, put myself last, adored him, let him know how special he was, but in the end as I saw myself as "less than" so did he and treated me as such.
My best advice at this point is to focus on you, what you want in life and set in place plans to get it for you, your own home, new job, studying, travelling, whatever it is, get it for yourself rather than live it adjacent to someone else. That way it is yours, on your terms and nobody can take it away.
