I'm kind of hurrying this out, so. Yeah. Also, it is quite long. Just skip to the end for the question. I can't make anything short these days...

I am almost 19 years old. I have one sibling - a 29 year old half-brother. He's been in and out of my life since I was a child, and it seems our relationship has actually grown because of it. "It's like we're making up for loss time," he once said. Either way he is very close to me. I look up to him despite all the horrible decisions he's made. To me he can do no permanent wrong. To him, I'm the best thing to have ever happened in his life. If not for me, he may not have even made it this far.

I've always gotten extremely jealous whenever he found a girlfriend. In my mind, I want to keep him to myself. I don't want anyone else 'stealing' his affection. I know it's silly and childish and irrational, but it's true. I feel like if I let him go to another woman, he'll forget about me. I won't be his favorite person anymore.

He's gone through 2 failed relationships since I started middle school. The last one was particularly painful for all of us. Now he's decided to date one of my relatively close high school friends. The 10-year age gap doesn't bother me as much as it should (bothers my parents, though...). It's the fact that he's dating someone I know and that I introduced to him and now he's become absorbed in talking to her all the time. I feel like she took him away from me. I feel like I'm not good enough for him anymore. And it's made me quite frustrated as of late.

Again, this is all irrational. I know that. I'm just being needy. And no, this isn't something incestuous. I don't even have a proper sex drive. Everyone totally still has cooties to me. I don't love him in a physical sense - more like in a very deep spiritual and emotional way.

So my question is, Subeta: How do I get over my blatant jealousy issues? And, alternatively, do I actually go and talk to him about this? He knows I'm quite obsessive over him and makes 'yandere' joked about it all the time. I just wonder if he knows how serious I feel...

I think you should talk to him about it, and seeing as how his girlfriend is one of your friends, bring it up with her, depending on how close you are to her. It might actually be in your favor to have his girlfriend being one of your friends. I think it would make it easier for you because then you wouldnt have to worry about him being with someone who didnt like you and trying to drive him away from you. If you are pretty good friends with her, i would definitely talk to her about it too. Let both of them know how you are feeling, and see what they think about it.

you should definitely go and talk to him about it. i have that SAME exact problem, being jealous of his girlfriends and them being his number one girl instead of me. it'll solve everything, i promise you. good luck. (:
