Here's my take on it. I found it rather odd how you worded the first part of your rather long sentence...even if she does leave, you'll see her again and keep in contact I'm sure since she's leaving not to get away from you.
She may say to you she doesn't love him, just so that you don't pick on her as you've probably made it very clear to her you don't like the guy as you mentioned. It's very very hard having a brother who doesn't like the guy you are in love with - trust me on this one - I went and married the guy anyway (and although many do have happy endings to it, mine didn't, lol).
So, my suggestion is to A) Question why she wants to get married to a guy she says she doesn't love (is it money or maybe your feelings?), or B) Let her do her own thing - you'll always be a part of her life even if you never get on with her fella, although for her sake it would be good if you at least tried as hard as you can...
Hope this helps somewhat :)
odalay talk about jerry springer lol sounds like your sisters young an going through a phase
A sister in law, by definition, is the sister of your wife. As long as you aren't still married to your wife, it would be legal. A sister-in-law can also be your brother's wife. You can marry her provided she is not still married to your brother.
Not if he is still married to your sister.
Yes, it is legal for your sister to marry your husband's brother.
He married his half sister, Ankhesenamun.
Well, he did. He married Hera.
Yes, as long as she is not already married.
No, Zeus did not marry Gaia. Gaia is considered to be the Earth Mother in Greek mythology and was married to Uranus, the sky god. Zeus was married to Hera, who was his sister as well as the queen of the gods.
No, a Catholic nun can not marry while she is a member of her order as she is considered to be married to God.
No It is strictly forbidden; per Quran explicit instructions, for one to marry his sister.
Only if you are no longer married to her sister or brother and she is no longer married.
Harry Potter doesn't have a sister. He married Ginny Weasley, his best friend Ron Weasley's sister.
Kevin who? Jonas? NO! he's married already
