Before i write what i want to write tellme ....

Is it weird ?? My mom and best friend says its weird .would you date your brother in laws identical twin brother ?...........< ugh you cant hit space > lol ....... little story time lol , LETS GOO !!!! . SO my sister and brother in law have been together since basically high sxhool ive always been one grade behind her am 28 she's 29 , her husband is 30 . I knew he had a twin but he wasn't around much when they was dating he lived with his grandparents and his brother lived with his dad . I met him when i was about 20 , we became close and also lost touch because his girl at the time didn't like me so i stepped aside .i dont like being around drama lol . Let's forward now to 2018 they broke up she got pregnant by an ex he got deployed to alaska . He lived over there for a very long time , he fell into a very deep hole of sadness i was also a mess i was in a very abusive relationship . We was there for eachother basically . Around 2019-2020 my brother in law proposed they got married 2022 . We became more closer he was already back home , we went on friend dates .movies went out to eat , now this is November2023 we spend it together at his place Thanksgiving < he had a bad fall so he was put on bed rest > . Feb 2024 he confessed he liked me and that his feelings to me are more than a friend wise , i told him the same . Around march April he asked me to be his gf . < here comes on the why ppl find it weird > . " oh but he as your sister's husband face " TF i dont see it like oh am falling for my sister's husband . Because thats how ppl see it . No yes they are twins YET THEY ARE SO DIFFERENT in so many ways . < you know> . My sister and brother in law are 100% in with us in being together just my mom is making weird like i want my sister relationship thru him < hope that makes sense >
