@roseywill,
Forgive me if I answer wrong but I am going based on what I got outside of all your abbreviations.
So you are 25, with a 23 year old for one year, whom is still in school. You want to marry him, but he didn't want to marry you until he was drunk and admitted he would like to marry you in about 10 years. Now you aren't sure if you want to marry him or get your PhD. Not that it seems to matter as your parents are picking out different men for you to see?? Sorry I am a little confused... but based on this my advice would be
1) you are 25, an adult, your parents cannot force you to stop dating someone and pick another person. Sit them down and nicely tell them to butt out of it.
2) You have been together a year... give it time before you think marriage.. What happens if you marry him, move in and 6 months later he is under your skin because of how different you both live. Being 23 the odds are he doesn't know what he wants... those are few and far between.
3) If, what I got it correct, you want to tell him that you want to get married sooner than 10 years because your parents are picking different men, I'd advise not to. It sounds a little creepy.. you can however talk to him about it without mentioning the whole parents thing, nobody wants to marry into a family where they automatically thinks their in-laws hate them before they walk in the door... just tell him your life plan, tell him you want to get married in 5 years or 3 or whatever. If he bales, then he wasn't the right guy anyway!
Good luck
