I totally understand the forever alone but happy about it feels. I felt that way since my parents got divorced. The thought of close relationships, even romantic ones, didn't appeal to me. I was just being silly, though. I was grieving over what I saw as the loss of my family. Those of us who come from nontraditional family situations experience this, I think, at one or another point in our lives.
I've never had an actual relationship. When I was younger, as I said, I hated the idea. Then I gained lodes of weight and was too insecure. Finally as I become healthier and more confident, I realize I'm not a ladies' man. It's just never really worked out for me. I know I won't be in a relationship that has a romantic/sexual aspect, just because it would be against my peace of mind. I've tried it, and it's honestly not for me. As much as I would love to go out and have hookups and what-not, like my friends, I just can't. It's not who I am.
However, it is not natural, nor God's plan, for people to be alone. Even those of us for whom celibacy is a real and probable reality, extreme solitude is not necessarily a part of that (hopefully not, anyway.) There can be intimacy outside of romantic and/or sexual relationships. There's intimacy between people in monastic communities, between family members in a home, between people who worship together, or even people who work together. This is where we need to find intimacy, especially if we're experiencing celibacy.
So, in short, while it's not strange for you to say you want to be forever alone, it's an entirely different situation when you're actually living this out. You'll see that you need companionship and intimacy. We all do. Solitude, while it's nice as a break from life once in a while, is easier said than done in the context of a lifetime.
I'm inclined to tell you to check out this song/video. It always cheers me up when the whole celibacy thing gets me down. https://www.youtube.com/watch?v=S5C8D2hI6UY
Don't plan to be alone. If it's something that the Lord wants for you, He'll give it to you in doses you can handle. Don't go and seek out this sort of thing, it's really not good for you.
