My best friend just proposed to a girl in grade 10.

[LostAngels]

My best friend's name is Mark. He's a lanky native kid with glasses, and the biggest heart I've ever seen in a guy my age.
He's in grade 12, and began dating a girl named Taylor just at the beginning of this school year. He's convinced she's perfect, she's the one, and all that.*
I've seen her treat him like absolute shit. This girl is so incredibly immature, and he knows that I can't stand her.*
I often make jokes about how he should get another girl's number, etc.*

He bought her a dozen roses one day, surprised her at school, and she was humiliated and got angry. She hated me from the beginning because I'm his best friend, and she knows that him and I have had deeper moments than they ever have.*
I love him more than she ever could, but no, I am not in love with him.*
I was happy for him because he was happy, but inside, it tears me up to see him treated so unjustly considering the amount of love he has to give.*
I've been waiting for him to find someone better.
I just found out they are now engaged, and I feel incredibly hopeless here. I want him to have the best, because he deserves nothing less. I am very protective over him in a sisterly-manner, And now I also feel obligated to make amends with Taylor and just let things be.*
But I can't bring myself to do that. It's wrong.*
I also feel like he's being selfish here. She just turned 15, and as much as I can't stand her, she has a lot of life to live.

How can I try and convince him this isn't the right option right now, without him getting upset or angry?*
How do I deal with this situation?

First things first, I doubt this relationship will last to the point of marriage. She's in grade 10, and he's in grade 12, making him nearly 18, which means...soon, it will be illegal for them to be together to begin with. Not that age is a huge difference here, and the age gap isn't that big, but if her parents got wind of an engagement between the two of them, I don't think they'd be very happy.

I know how disappointing this is for you, since you genuinely care for your friend, but sometimes, we have to let them make mistakes on their own. Otherwise, they won't learn what's right or what's wrong. Obviously, this girl is all wrong for him, but he just doesn't see it yet because he's blinded by love. After some more time together, he'll realize that she's not right for him, or he'll do something that outwardly ticks her off and she'll end it. You could bring up to your concerns to him, just by being honest. Let him know that you're not trying to upset him, but you just want to be honest with him for a minute, and then bring up your concerns. Otherwise, let him live and learn by himself. If you don't let him to do this, he'll always be blinded by love and not know what the difference is.

Hi there, i'm sorry to hear about your situation. The only thing that i can suggest is being there for him. He probably is going to need you, and as it was said above, share your concerns with him. It's normal to watch out for your friends, it means you're a good friend at that, but try not to let your caring nature get in the way of things, maybe he sees something in her that's genuine, and if that's the case, he's gunna want his best friend to enjoy it with him. However, if that's not the case... he'll eventually get fed up with being treated the way she treats him and leave, then everything will go back to normal.

I really doubt that their relationship will work out, especially if they are already engaged after only a couple months. He is probably just so happy to have a girlfriend, and he's still in the 'honeymoon' stage where he is blind to all of her flaws.
Sadly, there's not much you can do but just be there for him. He will have to learn for himself and see for himself just how bad for him she really is.

I am almost positive it isn't going to work. But you are going to have to let him make his own mistakes on this one, whether they get married or not. He doesn't seem to want to listen to your advice on his girlfriend, and I don't think you are going to get him to see the light. He is just going to have to come to terms with how awful she is himself. Besides, that lesson will stick more anyway. In addition, you have no need to apologize to Taylor. There is nothing to make amends for. She's a bitch, and that's that. You aren't obligated to get along with her.

Just make sure to be supportive when they break up... shouldn't take very long.
