agree with what lee said about the whole underage thing.

now, parents do not dictate your life, they have no rule even though they would like to think so, that being said it is real easy to follow what i say because i have left my family before and not spoken to them inawhile. if you have never done that, it is a very hard things to fo through.

wow, he truly loves you, to say "to hell with my family" the people who have known me my whole llife, who have been there for me through thick and thin, supported me, love me no matter what (from a mothers standpoint even if parents are mad at you and don't speak to you or say hateful things, they still love you) and go to you and make his life all about you! you should be so lucky for that!

entertain the waiting idea, if you are trying to make peace i have been with my partner for 4 years and waiting

your families in the end, will see how serious it is if you stick it out and go through with plans. they just don't see it as serious so they are acting as such.
so if you are over 18, it's your life, your rules, no compromises (save that for you and your spouse)
personally if i mary my partner i will be the only one amongst my siblings who "mother in law" loves me, (she already told me) all my other siblings theirs don't so you don't have to like them but eventually get along with them. everyone calms down over time
