It is his fault. Either that or you gave him no signs it wasn't going well and have been faking your happiness instead of talking about your issues, then its your fault.

Congratulations on making your future breakup that much more awkward.

Thanks for the tip. From now on, whenever things are shaky between me and my gf, I'll throw a house party and invite my family. She won't be able to reject if family is involved

That's awful you are going to make him suffer, tell him as soon as possible that you don't want to marry him...

You didn't have to say yes just because other people were there. You could have taken him aside and been honest- now the breakup is going to be even worse. You should also tell him that the next time he proposes, it would be better if it's in private so the other person doesn't feel as though they're obligated to say yes.

i would not want to make a public proposal anyway. too much risk of backfiring badly. as the "boyfriend" will soon experience.

Ya what a conundrum I probably would have said yes too.. Indeed your life sucks.

You need to tell him immediately. It's nice you didn't embarrass him in front of everyone but you need to tie this off before it gets worse.

Well now is the part where you tell him you told him "yes" to avoid embarrassing you both in front of his family.. and get out of the engagement lol

Deal with it.
