I was a pre-engineer student before. I learned those glass making etc in highschool. It is a very hard process. Like everything that you've work hard for, it will be worth it. So same as the relationships. As for that glass, it will become same as the first one if the maker is good and/or he/she is the one who made it at first. Same as the relationship, if your relationship have something wrong, it can be corrected by the same people involved, it is you and your partner. No one else. No one must intervene and meddle. They can give advised but at the end of the day, you and your partner will decide.
