Is it wrong for liking your sister-in-law?

She is not blood related, only through marriage. Go for it.

How is she your sister-in-law? Was she married to your brother?

Please help us to understand the relationship. Is she your spouse’s sister or is she your sibling’s ex spouse? In the latter case, she is no longer your sister-in-law.

Either way, it will probably equate to trouble with the family if you make a pass. And no, it probably isn’t weird. From the description though, it sounds more like lust than liking her.

I’ve got it. The only way she could be single, and your sister in law, is if your sisre’s husband has a sister’ That means you are only related because your sister got married. In fact, you can call her you sister in law, but you aren’t related at all’ If she isn’t a minor, then there’s no issue.
Just remember, her family does have a link to your family. If you mess things up…..

She is my sister’s husband sister.

Then you should be in the clear from a relationship standpoint. She isn’t your sister-in-law. Still, there is caution to be taken. Get to know her well and find out if there is any mutual attraction. Good luck and keep us posted.

If you’re single and she’s single, go for it.

Have fun. Why not? Just remember that if it ends ugly, it will have long standing effects.

Your sister’s husband’s sister is not your sister-in-law. She’s nothing to you. There’s no reason not to pursue something, as long as she’s also interested.

Good point by @dappled_leaves. Your sister’s husband is your brother in law, but his sister has no title.

I have this golden rule, if it gets hard, then trust your blood flow.
Okay, so it doesn’t rhyme, no one’s perfect.

Jump on it! Better to risk a flaming shoot-down than fret over a missed opportunity.

In that case, sure. Depending on family dynamics, I might have a conversation with your BiL first.

“Your sister is really nice, I’d like to get to know her better, would you be okay with that.”

I only say that because I wouldn’t want to cause issues for my sister in her marriage.

I know someone whose current spouse was once their in-law—they had been married to siblings. Neither was happy and they realized they were a great match, so they divorced the siblings and eventually got married. It was awkward that their step-kids were also cousins, but it’s been decades and they still have a very strong marriage and the scandal is far behind them.

I agree with those who suggest that you should have a conversation with your Brother-In-Law first, to see if it would cause any issues with the family politics.

Go for it dude.

I agree with checking things out with your sister and b-i-l and then take it slowly. she is really hot. is fine but there has to be more. Remember how difficult it was to disengage with your last girlfriend?
