So my sister has a new boyfriend an he is the sweetest guy ever. He is so cute and treats my sister so well:) I am really happy for her, but IIN to be SO jealous at the same time? I'm in a relationship as well and I've been with my bf for almost two years. We have our ups and downs, lately we haven't been so good :/ I love my bf so much, but I can't help having a huge crush on my sisters bf! Ughh.
