>she gets slim or transforms and maybe you find her attractive but probably not>you decide decades later you're not going to do any better and settle for her>you have sex with her out of pity, maybe even date her a little, then dump herno attraction means no relationship, people in sham relationships will try to convince you otherwise.

don't go down the path of oneism, 99% of the time it just leads to misery and the other 1% of the time it's a crap shoot. if you are a young guy now, just find another girl and it will be easy to forget about her with another girl in the picture you are trying for.
attraction isn't complicated, be tall, be in relatively good shape and just don't be horrendously ugly. if you have other issues work on them and you'll see returns
