Please let us help you if you continue believing that you will never find someone to love.
If you do find someone and you feel confident enough, just remember:
-Let the relationship develop at its own pace. If you meet a girl and come on as too strong to her, she may view you as desperate, creepy, or anything similar.
(Of course, you are not a creepy person. Being on the spectrum is just a part of your essence and be open about it to her as much as you can. If a girl you meet rejects you just because you're on the spectrum, forget about her and let us continue helping you.)
-Compliment her. Say the compliment as normal as you can. Girls like guys who have self-confidence instead of an ego.
(Of course, you are not a selfish person. Let us help you gain more self-confidence which in turn, could help you meet a girl who understands you and you understand her.)
-Make her laugh or smile. Girls like guys who know how to make her feel good.
-Be a sincere person.
-Show her that you truly care about her. Show her that you're serious about her instead of lusting after her because girls (again) may view you as desperate, creepy, or anything similar. Ask a girl you meet about herself. Talk to her instead of trying to kiss her.
-Never compliment a girl about her physical appearance except maybe her eyes, smile, or her hair. Even better, compliment a girl about her personality or her laugh. However, NEVER compliment a girl in a sexual manner.
-Learn how to break what is known as the "touch barrier." When you feel like you understand a girl well enough, touch her in areas that to her are not dangerous such as her back, shoulders, or even her hands.
-Be happy for her whenever she does something great or whenever she feels bad about something, try to understand her feelings and try to tell her that you want to make her feel better.
