Is it normal to be hateful towards partners of your siblings? My brother is single yet if he met a woman and married her and had children I should be happy right, yet if he met a woman who loved him and hogged him I almost feel like I would make her life a misery. I know that makes me sound a cold selfish bastrd, but it is the truth. My family is mine, nobody else should be invited without my permission.
It may sound immature I don't know, but I feel I would threaten the woman to leave my brother alone and fck off out of his life just for my peace and calm. I'd hate my brother to have children, I would not want the responsibility of getting involved in stupid family stuff, birthdays, parties, babysitting, meh a pile of poxy stuff. I have enough stuff to pay for without the addition of a heap of brats. My mind just can't cope with new additions. I get used to the now, the here, I have always hated when the family changes, does anyone feel the same? Like if your dad died and your mom started dating another man, all that stuff just pees me so off. Meh.

Actually, I think those feelings are pretty common. We have a lot of attachment for our family members and don't like to see those changes happen.

My siblings moving on with their own families would be fine with me, but my siblings choice of spouses seems to indicate that they're purposely trying to make me jealous. Any of my childhood career ambitions are now replaced by their spouses as though they were trying to outdo me with their spouses. Essentially, the siblings are like Pokemon trainers and their spouses and children are the Pokemon, but I don't have a spouse of my own, so I don't have any Pokemon to send against them.

Well I had a long reply all set to post then the cat stepped on the keyboard.

The short of it is that your feelings are normal. BUT when you truly love someone, their happiness is the most important thing. If they find happiness with a mate then that overcomes the rest. If you were to act as you say you think you will, remember that it's your brother that would be hurt. When you love someone, you do whatever you can to keep them from pain.

My youngest son is married. I truly do love his wife. I didn't think I ever would. But the fact is, he's in love, she loves him and he's happiest with her. I don't have to live with her, he does. This is his choice to make and he's made it. In the end, my love for him far out weighs my dislike of his mate.

I dislike my brother's wife very much. I've never liked her. Ironically the things my brother dislikes about my daughter-in-law are the very things I cannot stand in his own wife. But again, you have a choice, lose your brother and damage that relationship forever or accept the things you cannot change. Love always wins in the end.
