Ok so he's not my brother in law....
My sister has been dating this guy for about 4 years. They are now 25.
Anyway his older brother asked me out recenently. We've also been close and have had fun together. He was dating this gir; for 2 years that no one liked. I broke up with my boyfriend of over 3 years almost a year ago.
So we went out. Had a great time. I feel like he's someone that could be "the one". We know everything about each other. We are the same age, a lot in common. We both get along with each others families and connect so well...... We didn't do anything other then kiss. But we asked our respected siblings about what they think and they are completely against it.
My sister says it might be selfish, but she thinks it would ruin things between them. They have a good relationship. I can acknowledge that things would be awkward if things didn't work out. But now we dont know what to do..... I know that he would treat me like a princess and visa versa... We are both mature, professional people.
I'm pretty broken hearted over this. and just looking for opinions.... Is this terrible? Am I crossing the line? What would you think?
