I am very conflicted...

Backstory: We just moved to be closer to my boyfriend's family.

Me and my boyfriend were engaged but he broke it off today because I called him out on a tantrum.. (He seemed upset at the window blinds being open when he woke up.) I love sunlight. I noted I was worried about him maturing because that wasn't cool.  Turned out to be a misunderstanding. But he doesn't stop, he breaks off the engagement, he kept saying "it's not mature for two people to live together and have access to both bank accounts. We need to separate everything." He always takes it too far...

The problem is, I just had the best day of my life the day before with his brother [31 M] who looks like him, talks like him.. Yet he is WAY more mature, logical.. Frankly more like me. We think so much alike. I can't stop myself from wishing I met him first not his brother..

Me and bf patched things up.. But I'm laying here processing everything.. I asked myself.."Do you love bf?" ... I didn't feel anything. Yet my heart now races for the brother..

I hate myself for this.. And even if we broke up, I wouldn't persue the brother because that is fucked up.. I can't turn brothers against each other for a stupid woman. I need any insight I can get as I don't have friends here I can trust with that yet.. And all our old friends are both me and the bf's friends. Pls help..
<bot>: My boyfriend has been acting like a man-child for 5 years. We move and I meet almost his twin that has all the good qualities, plus we're both logical and always on the same wavelength.
