I still don’t see how you get around the p’ru urvu issue. Everyone agrees that’s a chiyuv, which requires getting married first. From what you’ve said so far, it seems to me that your only reasons for not getting married are that marriage is difficult, inconvenient, possibly won’t turn out the way you expect, etc.. I don’t think these are legitimate reasons to be m’vatel an aseh.
Obviously you need to wait until you’re ready, and it’s nobody’s place to rush you into it, but I don’t see how you can decide to never get married.
