<human>: So, I've been having lots of trouble getting into a real relationship since back in high school because I've come to realize that nearly all the women who I'm attracted to are older than me. While I'm perfectly aware that it is entirely possible for me, a 19M to date a, say, 21F, the odds of such a relationship realistically succeeding are pretty slim. 

I've been in two serious relationships in my life, both with older girls, and they both resulted in me being cheated on (with significantly older men), which has made me feel rather inadequate due to my age. Now, I don't date older girls because I'm sexually attracted to girls older than me, but because I find women who are mature, respectful, ambitious, and overall secure and happy with themselves to be the most attractive. Obviously there's a physical attraction too, but beauty lies in the eye of the beholder, so that aspect is entirely subjective.

So my real problem lies in the fact that I am finding it extremely difficult to find a girl who has the qualities that I find attractive, and is younger than me. So am I just unlucky here in that I can't find that girl? Or am I doing something wrong? I'm no Ryan Gosling, but I take care of my body and would consider myself at least adequately attractive. I have a job, good social life and friends, hobbies, etc. Is it really just my age that is resulting in me having no success with these older girls?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I'm only attracted to older girls these days, no success with relationships, looking for advice on how to move forward.
