If you’re looking for a real answer - and a solution - I suggest you seek counseling. You have a lot to sort out and it’s confusing to try to sort it out all at once, don’t you think? Whatever your disability is - physical, psychological, a combination - has it affected your self esteem? If so, how can you get that headed in a more positive direction? That’s the first priority - you’ll be happier in your life no matter what your single or married state.
Next important issues - why are you only attracted to younger women? Is it for a pure reason, or do you not relate well with gals nearer your age bracket? What I mean is, are you looking at the woman as a whole person or as a fantasy object to some degree? Can you develop the skills to relate to a woman on multiple levels? I don’t mean we are always perfectly free of preferences, but we need to not give them more weight than is appropriate.
To give an amusing example: I used to really go for blond guys - and the blond guys I dated gave me grief!

So now I might go for a brunette, LOL! I’m a bit paranoid of blonds now!
Plus, the better you know yourself and take a mature, balanced approach, seeing yourself as God sees you, the easier it will be to find women who are balanced and mature and humble - the kind of woman who would make a better wife.
But before you get too far along at that stage of the game, you should pray and discern what vocation God is calling you to. This should be easier if you’ve resolved some of those basic issues about yourself.
Hope this helps.
