As Aspies we tend to be all or nothing with no middle ground. For me, it was either she's my dream woman or she's pointless to talk to, since the relationship is likely to end sooner if there isn't as much of a connection. But what I realized is, am I really happy dreaming about the perfecting woman and not having fun with other women? Not really. While I have a good imagination and can live in my head sometimes, it obviously isn't fulfilling if I've posted about 100 times on this site with about 80 or 90 of the posts about my lack of a dating life.
What I also realized was that other beautiful women, who might sexually attract you and not seem like your type, 1.)Exist more than you'd think, 2.)Maybe they might surprise you and make a good girlfriend.
By having a scarcity mentality, you're putting a lot of pressure on yourself by thinking, "If I don't get this girl, my life is over." I may not see another girl as beautiful as the one I just got rejected by for another month (especially given my lack of a social life) but I will see another one just as beautiful eventually.
