I can't speak for all Aspie men, but when I read the "I want a girlfriend more than anything" posts on here, the depression and lack of self-esteem is obvious, and that's the core problem.
The reason for the depression and lack of self-esteem is a lack of meaning, focus...a passion to live your life for.
A girlfriend or wife will never be this passion...she's only someone to share the happiness with. No woman, no matter how great of a person, is going to make a sad man happy.
Unfortunately, video games, anime, a tv show you like, your stamp collection, etc., are not a passion.
A passion is something you couldn't live without, and not out of obsession, but because like a family member, it means that much to you and how you define yourself as a person.
For me, it's music...not only listening to it, but playing it. I didn't have a piano to play for a few years, and bought one in late February, early March. On top of joining a band right around that time...both the band, and having an instrument to play...something that I'm talented at and could potentially benefit other people (by them hearing me play) catapulted my confidence and self-esteem and a feeling of meaning in life.
Because of this, I'm at a point where a girlfriend is a low priority. If a cute, compatible woman wants to come along for the ride, fine, but I don't need her to be happy.
As Aspie men, a lot of us are introverts and have introverted interests. I'm not saying abandon those interests, but I'm saying don't spend your life playing RPGs or looking at hentai and find something that will benefit yourself in ways you could never imagine.
